A sphere of radius 5 cm is melted and recast into spheres of radius 2 cm each. How many such spheres can be made?
15
16
17
18
15
Let the number of small spheres be n.
According to the question
⇒ (4/3) × π × R3 = n × 4/3 × π × r3
⇒ R3 = n × r3
⇒ 53 = n × 23
⇒ n = 125/8 = 15.625
Therefore 15 complete spheres can be made with some extra molten material left.
Mistake PointsIn this question does not take the 16 as an approx answer, because such type of question is always 15.625, take the integer value only. 15 is the right answer.
The average of 18 numbers is 52. The average of the first 8 numbers Is 62 and the average of the next 7 numbers is 45. If the 16th number is 6 less than the 17th number and 17th number is one more than the 18th number, then what is the average of the 16th and 18th numbers?
40.5
40
39
39.5
40.5
Average of 18 numbers = 52
Sum of all 18 numbers = 18 × 52 = 936
Average of first 8 numbers = 62
Sum of first 8 numbers = 8 × 62 = 496
Average of next 7 numbers = 45
Sum of next 7 numbers = 7 × 45 = 315
Let the 18th number be x
∴ 17th number will be = x + 1
∴ 16th number will be = x + 1 - 6 = x - 5
Sum of 16th, 17th and 18th number = 936 - 496 - 315 = 125
According to the question
⇒ x - 5 + x + 1 + x = 125
⇒ 3x - 4 = 125
⇒ 3x = 125 + 4 = 129
⇒ x = 129/3 = 43
⇒ 18th number = 43
⇒ 17th number = x + 1 = 43 = 44
16th number = x - 5 = 43 - 5 = 38
Average of 16th and 18th number = (43 + 38)/2 = 40.5
In the given pie-chart, how many persons are using train to reach their workplace?
380
360
320

If (2x + 3)3 + (x - 8)3 + (x + 13)3 = (2x + 3) (3x - 24) (x + 13), then what is the value of x?
-2
-2.5
1
-1.3
-2
As we know,
If x3 + y3 + z3 - 3xyz = 0, then x + y + z = 0
⇒ (2x + 3)3 + (x - 8)3 + (x + 13)3 = (2x + 3) (3x - 24) (x + 13)
⇒ (2x + 3)3 + (x - 8)3 + (x + 13)3 - 3 (2x + 3) (x - 8) (x + 13) = 0
⇒ (2x + 3) + (x - 8) + (x + 13) = 0
⇒ 4x + 8 = 0
⇒ 4x = -8
⇒ x = -8/4 = -2
If x - 1/x = 6, then x3 - 1/x3 is equal to∶
234
198
176
216
234
As we know,
x - 1/x = 6
Taking cube on both the sides
(x - 1/x)3 = 63
x3 - 1/x3 - 3(x - 1/x) = 216
(x3 - 1/x3) - 3(6) = 216
x3 - 1/x3 = 216 + 18 = 234
6 cubes, each edge 4 cm, are joined end to end what is the total surface area of the resulting cuboid?
496 cm2
416 cm2
576 cm2
208 cm2
416 cm2
Edge of each cube = 4 cm
If 6 cubes are joined end to end, then
Length of newly formed cuboid = 4 × 6 = 24
Breadth of newly formed cuboid = 4 cm
Height of the newly formed cuboid = 4 cm
As we know,
Total surface area of cuboid = 2 (lb + bh + hl) = 2 (24 × 4 + 4 × 4 + 4 × 24) = 2 (96 + 16 + 96) = 2 × 208 = 416 cm2
A boat can go 30 km downstream and 24 km upstream in 2 hours 27 minutes. Also, it can go 10 km downstream and 4 km upstream in 37 minutes. What is the speed of the boat upstream (in km/h)?
22
18
20
24
20
We can write, 2 hr + 27 min = 2 + 27/60 = 49/20 hrs and 37 min = 37/60 hr
Let speed of boat be x km/hr and the speed of stream be y km/hr
∴ Speed of boat in downstream = (x + y) km/hr
∴ Speed of boat in upstream = (x - y) km/hr
According to the question
⇒ 30/(x + y) + 24/(x - y) = 49/20
Suppose 1/(x + y) = a, and 1/(x - y) = b, then
⇒ 30a + 24b = 49/20 ----(1)
⇒ 10/(x + y) + 4/(x - y) = 37/60
⇒ 10a + 4b = 37/60 ----(2)
Multiply by 3 in equation (2)
⇒ 30a + 12b = 37/20 ----(3)
Subtract equation (3) from (1)
⇒ 12b = 49/20 - 37/20 = 12/20
⇒ b = 1/20
⇒ 1/(x - y) = 1/20
⇒ (x - y) = 20 km/hr
Speed of boat in upstream is 20 km/hr
The efficiency of A, B and C are in the ratio 5 ∶ 6 ∶ 9 Working together, they can complete a work in 18 days. In how many days can B alone complete 25% of that work?
16
10
18
15
15
The efficiencies ratios of A, B and C = 5 ∶ 6 ∶ 9
Total work = (5 + 6 + 9) × 18 = 20 × 18 = 360
25% of the total work = 360 × 25/100 = 90
B alone can complete the 25% of the total work = 90/6 = 15 days
36 persons working 8 hours a day can do 3 units of work in 12 days. How many persons are required to do 5 units of that work in 16 days, if they work for 6 hours a day?
50
60
55
45
60
Let the number of persons be x
As we know, Total work = Total work, so
(M1 × D1 × T1)/W1 = (M2 × D2 × T2)/W2
Given, M1 = 36 person, D1 = 12 days, W1 = 3 units, T1 = 8 hrs M2 = x person, D2 = 16 days, W2 = 5, and T2 = 6 hrs
(M1 × D1 × T1)/W1 = (M2 × D2 × T2)/W3
(36 × 12 × 8)/3 = (x × 16 × 6)/5
x = 60 persons

As we know,
⇒ (BC/PR)2 = ar(ΔABC)/ar(ΔPQR) = 9/16
⇒ 62/PR2 = 9/16
⇒ PR2 = 4 × 16
⇒ PR = 2 × 4 = 8 cm

The mean proportional between two numbers a and b is the square root of their product, i.e., x = √(a × b).
Third Proportional
For two numbers a and b, the third proportional c is such that a : b = b : c, which gives c = b2 ÷ a.
Fourth Proportional
For three numbers a, b, and c, the fourth proportional d is such that a : b = c : d, calculated as d = (b × c) ÷ a.
PA and PB are two tangents from a point P outside a circle with center O. If A and B are points on the circle such that ∠APB = 80°, then ∠OAB is equal to∶
45°
40°
55°
50°
40°
As we know,
⇒ ∠AOB + ∠APB = 180
⇒ ∠AOB = 180 - 80 = 100°
In ΔOAB
⇒ If OA = OB radius of the circle
∴ ∠OAB = ∠OBA
⇒ ∠OAB + ∠OBA + ∠AOB = 180°
⇒ 2∠OAB = 180 - ∠AOB = 180° - 100° = 80°
⇒ ∠OAB = 40°
If a3 + b3 = 5824 and a + b = 28, then (a - b)2 + ab equal to∶
208
180
236

208
As we know,
a3 + b3 = (a + b) (a2 + b2 - ab)
a3 + b3 = (a + b) (a2 + b2 - 2ab - ab + 2ab)
a3 + b3 = (a + b) [(a - b)2 + ab]
Given, a3 + b3 = 5824 and a + b = 28, then
5824 = 28 [(a - b)2 + ab]
[(a - b)2 + ab] = 5824/28 = 208

120 cm2
130 cm2
312 cm2
120 cm2
Given, a = 13 cm and d1 = 24 cm and d2 = ?
As we know,
a2 = (d1/2)2 + (d2/2)2
132 = (24/2)2 + (d2/2)2
169 = 122 + (d2/2)2
(d2/2)2 = 169 - 144 = 25
d2/2 = √25 = 5
d2 = 5 × 2 = 10 cm
As we know,
Area of the rhombus = (1/2) × d1 × d2 = (1/2) × 24 × 10 = 120 cm2
A sum of Rs. 12,800 is invested partly at 15% per annum and the remaining at 12% per annum simple interest. If the total interest at end of 3 years is Rs. 5,085, then how much money was invested at 15% per annum?
Rs. 5,300
Rs. 7,500
Rs. 5,800
Rs. 5,200
Rs. 5,300
Given:
Total amount = Rs. 12800
Partly at 15% per annum and the remaining at 12% per annum simple
interest.
Interest at end of 3 years is Rs. 5,085
Formula used:
SI = (P × T × R)/100
Where P = principal , T = time and R = rate of interest.
Calculation:
Let Rs. y invested at 15% per annum.
Money invested at 12% per annum = Rs. (12,800 - y)
Simple interest in 3 years = Rs. 5,085
Simple interest in 1 years = 5,085/3 = Rs. 1,695
Using the formula,
SI = (P × T × R)/100, for 1 year
⇒ y × 15/100 + (12,800 - y) × 12/100 = 1695
⇒ 15y + 12800 × 12 - 12y = 1695 × 100
⇒ 3y = 169500 - 153600 = 15900
⇒ y = 15900/3 = Rs. 5300
∴ Money was invested at 15% per annum is Rs. 5300.
Two pipes A and B can fill an empty tank in 8 hours and 12 hours respectively. They are opened alternately for 1 hour each, starting with pipe A first. In how many hours will the empty tank be filled?
9
Given:
Pipe A alone can fill the tank = 8 hrs
Pipe B alone can fill the tank = 12 hrs
Time ratio of Pipe A and B = 8 ∶ 12 = 2 ∶ 3
Concept used:
Efficiency is inversely proportional to time.
Calculation:
Efficiency ratio of pipe A and B = 3 ∶ 2
Total work = 3 × 8 = 24
Both pipes opened alternately for 1 hr
Total work in 2 hrs = 3 + 2 = 5
Work in 8 hrs = 5 × 4 = 20
Work in next 1 hr (9th) = 20 + 3 = 23
Remaining work = 24 - 23 = 1
B alone can work in 1 hr = 2
B alone can work in 1/2 hr = 1
So, the total work complete in hrs
Shortcut Trick
Total work = 24
Work completed in 2 hrs = 3 + 2 = 5
Work completed in 8 hrs = 20
work completed in 9th hr = 20 + 3 = 23
B completed remaining 1 work in = 1/2 hr
Total work completed in = hrs
**∴ The total work will be completed in hrs.**
The price of sugar is decreased by 10% By what percent can a person increase the consumption so that there is no change in the expenditure?
10%
100/11%
109/11%
100/9%
100/9%
Detailed solution∶
Let the price of the sugar be 100x
Price of sugar after decreased = 100x × (90/100) = 90x
Price ratio of sugar before and after = 100x ∶ 90x
As we know, consumption of sugar is inversely proportional to price
So, consumption ratio of sugar before and after decreasing = 90x ∶ 100x
Consumption increased by = 100x - 90x = 10x
Required percentage = (10x/90x) × 100 = (100/9) %
The value of is equal to∶

The sides of a triangle are 8 cm, 15 cm, and 17 cm respectively. At each of its vertices, circles of radius 3.5 cm are drawn. What is the area of the triangle excluding the portion covered by the sectors of the circles (π = 22/7)?
47 cm2
23.5 cm2
21.5 cm2
40.75 cm2
40.75 cm2
The sides of a triangle are 8 cm, 15 cm and 17 cm.
As we know,
17 = 8 + 15
289 = 64 + 225
289 = 289
Now we can say triangle is right angled triangle
Area of right angled triangle = (1/2) × Base × height = (1/2) × 8 × 15 = 60 cm2
Area Covered in triangle by 3 circles = (θ₁ /360) πR² + (θ₂ /360) πR² + (θ₃ /360)πR² = [(θ₁ + θ₂ + θ₃)/360] × πR²
As we know,
θ₁ + θ₂ + θ₃ = 180°
Area Covered in triangle by 3 circles = [(θ₁ + θ₂ + θ₃)/360] × πR² = [180/360] × [22/7] × 3.5 × 3.5 = 19.25 cm2
Area of the triangle excluding the portion covered by the sectors of the circles = 60 - 19.25 = 40.75 cm2
If tan 3x = cot (30° + 2x), then what is the value of x?
12°
18°
10°
15°
12°
⇒ tan 3x = cot (30° + 2x),
⇒ tan 3x = tan[90° - (30° + 2x)]
As we know, cot(90° - x) = tan x
⇒ 3x = 90° - 30° - 2x
⇒ 3x + 2x = 60°
⇒ 5x = 60°
x = 60°/5 = 12°

A shopkeeper sold two articles for Rs. 9831 each. On one he gained 13% and on the other, he lost 13%. What is the overall percentage gain or loss?
1.69% gain
6.5% gain
1.69% loss
6.5% loss
1.69% loss
SP of each article = Rs. 9831
CP of first article = 9831 × [100/113] = 8700
CP of second article = 9831 × [100/87] = 11300
Total SP of both article = 9831 × 2 = 19662
Total CP of both article = 8700 + 11300 = 20000
Total loss = 20000 - 19662 = 338
Required loss percentage = (338/20000) × 100 = 1.69%
In the given histogram, which class is the median class?
165 - 175
150 -155
155 - 160
160-165
160-165
As we know,
If number of the observation is n is odd, then the median is [(n + 1)/2]th observation.
If number of the observation is n is even, then the median will be the average of the (n/2)th and [(n/2) + 1)]th observation.
Total number of students = 15 + 13 + 10 + 14 + 12 + 6 = 70
Median = [(70/2) + (70/2 + 1)]2 = (35 + 36)/2 = 35.5th (36th) students (which comes in 160 - 165)
Number of students who lies (150 - 155) = 15 students
Number of students who lies (155 - 160) = 13 students = 16th to 28th
Number of students who lies (160 - 165) = 10 students = 29th to 38th
So, 35.5th (36th) students comes in 160 - 165.
If a train runs with the speed of 48 km/h, it reaches its destination late by 12 minutes. However. If its speed in 64 km/h it is late by 3 minutes only. The right time for the train to cover its journey (in minutes) is∶

Let right time for the train to cover its journey (in minutes) be x min,
As we know,
Distance = Speed × Time
Distance is same, then
According to the question
48 × (x + 12)/60 = 64 × (x + 3)/60
3 (x + 12) = 4 (x + 3)
3x + 36 = 4x + 12
4x - 3x = 36 - 12
x = 24 min

Sum of the two numbers = 26 (4 + 7) = 26 × 11 = 286
ABCD is a cyclic quadrilateral such that AB is the diameter of the circle circumscribing it and ∠ADC = 145°. What is the measure of ∠BAC?
40°
50°
35°
55°
55°
Given ABCD is a cyclic quadrilateral and AB is the diameter.
As we know, the sum of the either pair of the opposite angles of a cyclic quadrilateral is 180°
⇒ ∠ADC + ∠ABC = 180
⇒ ∠ABC = 180° - 145° = 35°
In ΔACB, if AB is diameter, then ∠ACB = 90°
⇒ ∠ACB + ∠ABC + ∠BAC = 180°
⇒ 90° + 35° + ∠BAC = 180°
⇒ ∠BAC = 180° - 125° = 55°
A sum of Rs. 18,000 is invested for 16 months at 8% per annum compounded half-yearly. What is the percentage gain at the end of 16 months, to the nearest whole number?
9%
11%
10%
12%
11%
⇒ Rate = 12%
⇒ Rate for 6 months = (8/2)% = 4%
⇒ Rate for 4 months = (8/3) %
Short Trick∶
Percentage gain at the end of 12 month = 4% + 4% + (4% × 4%)/100 = 8% + 0.16% = 8.16%
Percentage gain at the end of 16 month = 8.16% + (8/3)% + [8.16% × (8/3)%]/100 = 8.16% + 2.66% + 0.2176% = 11.0376% = 11% (approx)
In Δ ABC, ∠A = 30°. If the bisectors of the angle B and angle c meet at a point O in the interior of the triangle, then ∠BOC is equal to∶
75°
105°
120°
90°
105°
As we know,
If the bisectors of the angle B and angle C meet at a point O in the interior of the triangle, then
∠BOC = 90° + ∠A/2 = 90° + 30°/2 = 90° + 15° = 105°
What is the sum of the digits of the least number, which when divided by 12, 16 and 54, leaves the same remainder 7 in each case, and also completely divisible by 13?
36
16
9
27
16
Firstly, find LCM and as it leaves remainder of 7 then the number is LCM +7
The number can be 432 + 7 = 439
But the condition is, the number should also be completely divisible by 13
Let multiply in 432 by x, so number become (432x + 7). So this number should be divisible by 13, so we find out the value of x
According to the question
(432x + 7) ÷ 13
= 432x/13 + 7/13
= (33x × 13 + 3x)/13 + 7/13
= (33x × 13)/13 + (3x + 7)/13
(3x + 7) divisible by 13 so, we put x = 1, 2, 3, 4, 5, …
When we put x = 2, then number become (3 × 2 + 7) = 13 which is divisible by 13, so x = 2
432x + 7 = 432 × 2 + 7 = 871
Sum the digit of the number 871 is = 8 + 7 + 1 = 16
A ladder leaning against a wall makes an angle θ with the horizontal ground such that sin θ = 12/13 If the foot of the ladder is 7.5 m from the wall, then what is the height of the point where the top of the ladder touches the wall?
15 m
8 m
18 m
12 m
18 m
sin θ = 12/13
As we know,
sin θ = Opposite angle of θ/Hypotenuse = BC/AC = 12/13
Using Pythagoras theorem
(Hypotenuse)2 = (Perpendicular)2 + (Base)2
(AC)2 = (BC)2 + (AB)2
132 = 122 + (AB)2
169 = 144 + (AB)2
(AB)2 = 169 - 144 = 25
AB = √25 = 5 unit
AB (5 unit) = 7.5 m
1 unit = 7.5/5 = 1.5 m
Height of the point where the top of the ladder touches the wall BC = 12 unit
12 unit = 12 × 1.5 = 18 m
A shopkeeper marks his good at a price such that after giving a discount of 25%, the gains 20% If the marked price of the article is Rs. 736, what is the cost price of the article?

Rs. 440
Rs. 455
Rs. 460
Marked price of the article = Rs. 736
Sp of the article = Rs. 736 × (75/100) = Rs. 552
Cost price of the article = Rs. 552 × (100/120) = Rs. 460

In an examination, 48% of candidates passed in science and 56% failed in mathematics. If 32% failed in both subjects, then what present passed in both subjects?
28%
24%
32%
22%
24%
Percentage of passed students in science = 48%
Percentage of failed students in science = 100% - 48% = 52%
Percentage of failed students in mathematics = 56%
Percentage of failed students in science and mathematics both subject = 32%
Detailed solution∶
From the figure
Percentage of failed students only in maths = 56 - 32 = 24%
Percentage of failed students only in science = 52 - 32 = 20%
Total percentage of failed students = 20% + 32% + 24% = 76%
Percentage of passed students = 100% - 76% = 24%
Short Trick∶
Percentage of failed students = 52% + 56% - 32% = 76%
Percentage of passed students = 100% - 76% = 24%
The radius of a cylinder is increased by 120% and its height is decreased by 40%. What is the percentage increase in its volume?
190.4%
175.4%
180.6%
212.8%
190.4%
Detailed solution∶
Let the radius and the height of cylinder be r and h cm, respectively.
Volume of cylinder = π r2h
When the radius is increased by 120%,
New radius of cylinder = r × [220/100] = 2.2r
When the height is decreased by 40%, then
New height of the cylinder = h × 60/100 = 0.6h
New volume of the cylinder = π × (2.2r)2 × 0.6h = 2.904 × π r2h
Volume increased = 2.904 × πr2h - πr2h = 1.904 πr2h
Volume increased in percentage = [(1.904 πr2h)/πr2h] × 100 = 190.4%

Concept:
Divisibility law of 8 ⇒ A number divisible by 8 if its last three digit is divisible by 8
Divisibility law of 9 ⇒ A number is divisible by 9 if sum of its digit is divisible by 9.
Calculation:
⇒ 7 digit number 74x29y6 is divisible by 72 means number divisible by 8 and 9 both.
Last three digit 9y6 should be divisible by 8 then we put y = 0, 1, 2, 3… When we put y = 3 then number become 936 which is divisible by 8.
⇒ 74x2936 should be divisible by 9, then sum of its digit
⇒ 7 + 4 + x + 2 + 9 + 3 + 6
⇒ 31 + x
If we put x = 5, then number become 36 which is divisible by 9.
⇒ (2x + 3y)
⇒ (2 × 5 + 3 × 3)
⇒ 10 + 9
⇒ 19
∴ Minimum value of y i.e. for y = 3, value of (2x + 3y) is equal to 19

Read the following passage and answer the questions given alter it.
The ocean will not look the same color in the future.
Essentially, climate change will make the blues of the ocean bluer and the greens greener. Scientists from MIT. Boston, figured this out by creating a global model that simulates the growth of a tiny creature that lives in the oceans and affects the color we see. Their research was published in the journal Nature Communications.
The ocean looks blue or green to us because of a combination of how sunlight interacts with water molecules and with whatever else lives in that water.
The molecules in water absorb all but the blue part of the spectrum of sunlight, and the water reflects that blue color back. That's the color we see.
The water looks greener when it has more phytoplankton, tiny, microscopic organisms that, like plants, can use chlorophyll to capture mostly the blue portions of the spectrum of sunlight. They then use photosynthesis to create the chemical energy they need to live. When there are more of these creatures in the water absorbing sunlight. they make the water look greener. Conversely. if there are fewer phytoplankton. the water looks bluer
The creatures growth is dependent on how much sunlight, carbon dioxide and nutrients are around. Climate change is altering the ocean currents. meaning there will he fewer nutrients for phytoplankton to feed on in sonic areas, so there will be a decline in their number in those regions.
Since the 1990s, satellites have taken regular measurements of how much chlorophyll is in the ocean. Those levels can change because of weather events or because of climate change.
The study predicts that the blues will intensify. most likely in subtropical regions where phytoplankton will decrease. These are areas near the equator like Bermuda and the Bahamas that are already quite low in phytoplankton.
Regions where there are a lot of nutrients, like in the Southern Ocean or parts of the North Atlantic, will see even faster-growing phytoplankton because those waters are warming with climate change.
Those waters will look greener.
Climate change will bring a color change to half of the world's oceans by the end of the 21st century, the study says. That's bad on several levels: For one, phytoplankton removes about as much carbon dioxide from the air as plants and help regulate our climate, research shows. They are also key to other animals' survival. “Phytoplankton are at the base, and if the base changes, it endangers everything else along with the food web, going far enough to the polar bears or tuna or just about anything that you want to eat or love to see in pictures. "said Stephanie Dutkiewicz, a principal research scientist in MIT.
Which statement is not true according to the passage?
Phytoplankton has a key role in the survival of other animals.
By the end of 21st century the colour of ocean waters will change.
More blue colour in the ocean will affect the climate change.
In subtropical regions phytoplankton will decrease.
More blue colour in the ocean will affect the climate change.
As per the passage,Climate change will affect the colour of the ocean and make it more blue and not the other way around as given in option 3.
Thus, Option 3 is not true according to the passage and hence is the correct answer.
Rest of the sentences are given directly in the passage and hence are true.
The passage is mainly about:
The change of the ocean color due to climate change.
Why ocean water looks blue.
How the growth of phytoplankton will impact the food web
The growth of phytoplankton in the ocean.
The change of the ocean color due to climate change.
If one reads the passage carefully, one can conclude the answer easily.
Throughout the passage, it has been mentioned about climate change causing the change of the ocean color. Even the passage starts with the same thought. In the passage, it is mentioned how the color gets changed due to the relative growth of phytoplankton which in turn is affected by climate change. Thus it can be concluded that the passage is about the change of color of the ocean due to climate change.
Hence, option 1 is the correct answer.

The colour of the ocean depends on:
the growth of phytoplankton in the ocean.
the sunlight's absorption by the sea organisms.
water molecules absorbing the blue of the sunlight
the sunlight's interaction with the water molecules and sea organisms.
the sunlight's interaction with the water molecules and sea organisms.
In the first few lines of the passage, it is mentioned;
"The ocean looks blue or green to us because of a combination of how sunlight interacts with water molecules and with whatever else lives in that water."

Here, we have to assign an Article to noun 'war' to fill in the blank.
Now,
The article 'an' is used before a word beginning with a vowel sound and this is not applicable for the word 'war'.
We use 'any' to mean ‘it does not matter which or what’, but in our case, we are talking about some war that happened in South Africa specifically and not any random war.
Now, the article 'the' is used to point out some definite/particular thing. We are not sure about which particular war that has happened in the history of South Africa we are talking about.
The Indefinite Article 'a' is used in its numerical sense of one. e.g- Twelve inches make a foot. (a foot = one foot, 'a' denoting 1)
So, in our case, we are talking about some indefinite but one single war that happened in the history of South Africa.
Thus,During a (1) war in South Africa, is the correct usage.
Select the most appropriate option to fill in blank no. 3.

First, we should understand the usage of these interrogative and relative pronouns:
Who is a subjective-case pronoun, meaning it functions as a subject in a sentence, -Who would like to go on vacation?
Whom is an objective case pronoun, meaning it functions as an object in a sentence.--I do not know with whom I will go to the party.
Whose is the possessive form of who. It means belonging to whom.
For example, Carl knows the girl whose phone was stolen.
Which is used in questions as a determiner and interrogative pronoun to ask for specific information
For example: Which museums did you visit?
In the given blank, it is asking about who i.e. the boys.
Hence, option 4 is the correct answer.
Select the most appropriate option to fill in blank no. 2
