4

Why this answer is correct

Given:

Logic: If two same dice have one face common in them, then write it in clockwise direction starting from the common face, then the number with a same positional value of them will be the numbers opposite to them

In given figure, 3 is common between both dice. So we write,

(3-5-6) and (3-1-2) in sequential order.

It means (5-1), (6-2) are opposite to each other.

The remaining face, (4-3) becomes opposite to each other.

So, the number opposite to 3 is 4.

Hence, 4 is the correct answer.

  4. DOption (d)

    17 : 238

View answer & explanation

Correct answer

Answer: (d)D.

17 : 238

Why this answer is correct

The logic followed here is:

Second number = (First number - 2) × First number

  1. 16 : 224 → 16 × (16 - 2) = 16 × 14 = 224

  2. 21 : 399 → 21 × (21 - 2) = 21 × 19 = 399

  3. 35 : 1155 → 35 × (35 - 2) = 35 × 33 = 1155

  4. 17 : 238 → 17 × (15 - 2) = 17 × 15 = 255 ≠ 238

Hence, 17 : 238 is the odd pair.

Alternate MethodThe logic followed here is:

(First number)2 - (First Number × 2) = Second Number

  1. 16 × 16 = 256 - (16 × 2) = 224

  2. 21 × 21 = 441 - ( 21 × 2) = 399

  3. 35 × 35 = 1225 - ( 35 × 2) = 1155

  4. 17× 17 = 289 - ( 17 × 2 ) = 255 ≠ 238

Hence, 17 : 238 is the odd pair.

    ii

  3. COption (c)

    i

  4. DOption (d)

    iv

View answer & explanation

Correct answer

Answer: (a)A.

iii

Why this answer is correct

FORMULA USED:

S.P. = (1-d1/100) × ( 1- d2/100) × M.P.

Discount = ( M.P. -S.P.)

Discount% = ( Discount/M.P.) × 100 

Where, S.P.= Selling price,   M.P. = Marked Price 

d1 and d2 are successive discounts respectively

CALCULATION :

Let us assume the Marked price to be Rs100 

on considering (i), we have

d1 = 25% , d2 = 25%  M.P. = 100

⇒ S.P. = ( 1- 25/100) × ( 1- 25/100) × 100 = 3/4 × 3/4 × 100 = Rs56.25

on considering (ii), we have

discount% = 40 M.P.= 100

⇒ discount% = ( discount/M.P.) × 100 

⇒ 40 = ( discount/100) × 100  ⇔ discount = 40

⇒ S.P.= ( M.P.- discount )  = ( 100 - 40) = Rs60

on considering (iii), we have

Buy 1 get 1 free

⇒ Marked price of 1 article is assumed to be 100

⇒ Hence, Marked price of 2 articles = 200

⇒ Since, 1 article is free. Hence, the customer will get 2 articles in Rs100 

⇒ So, we can say that the Selling price of 1 article  = Rs50

on considering (iv), we have

d1= 30%, d2 = 20% M.P. =100

⇒ S.P. = ( 1- d1/100) × ( 1- d2 /100) × M.P. = ( 1- 30/100)× ( 1- 20/100) × 100 = 7/10 × 4/5 × 100 = Rs56.

Hence,(iii) has minimum Selling price. So, it is more beneficial to the customer.

Question 52

A 640 metre long train travelling at 80 km/h overtook a 540 metre long train travelling at 72 km/h in the same direction. How long did it take the faster train to cross the other train completely?

  1. AOption (a)

    8 minutes 41 seconds

  2. BOption (b)

    9 minutes 09 seconds

  3. COption (c)

    9 minutes 01 second

  4. DOption (d)

    8 minutes 51 seconds

View answer & explanation

Correct answer

Answer: (d)D.

8 minutes 51 seconds

Why this answer is correct

Shortcut Trick

Relative speed (same direction) = 80 − 72 = 8 km/h

Relative speed in m/s = 8 × 5/18 = 20/9 m/s

Total distance to cover = 640 + 540 = 1180 m

Time = 1180 ÷ (20/9) = 59 × 9 = 531 seconds

531 seconds = 8 minutes 51 seconds

∴ The correct answer is 8 minutes 51 seconds.

Alternate Method

Given:

Length of faster train (L1) = 640 m

Length of slower train (L2) = 540 m

Speed of faster train (S1) = 80 km/h

Speed of slower train (S2) = 72 km/h

Formula Used:

Relative Speed (same direction) = S1 − S2

Time = Total Distance ÷ Relative Speed

Train 1: 640m

Train 2: 540m

S1 = 80 km/h

S2 = 72 km/h Relative Speed = S1 − S2 (Same Direction) Total Distance = 640 + 540 = 1180 m

Calculations:

⇒ Total distance to be covered = L1 + L2 = 640 + 540 = 1180 m

⇒ Relative speed = 80 − 72 = 8 km/h

⇒ Relative speed in m/s = 8 × (5/18) = 40/18 = 20/9 m/s

⇒ Time taken = 1180 ÷ (20/9)

⇒ Time taken = 1180 × 9/20

⇒ Time taken = 59 × 9 = 531 seconds

⇒ Time in minutes = 531 ÷ 60 = 8 minutes and 51 seconds

∴ The correct answer is 8 minutes 51 seconds.

Additional Information

Relative Speed Concepts

When two objects move in the same direction, relative speed is the difference of their speeds. When they move in opposite directions, relative speed is the sum of their speeds.

Unit Conversion

To convert km/h to m/s, multiply by 5/18. To convert m/s to km/h, multiply by 18/5.

Crossing Distance

When a train crosses another train, a bridge, or a platform, the total distance covered is the sum of the lengths of the two objects.

Question 53

In an assembly election of two candidates, the winner got 56% of the total valid votes. 5% of the total votes were declared invalid. If the total number of voters is 3,20,000 then what is the number of valid votes polled for the winning candidate?

  4. DOption (d)

    170240

View answer & explanation

Correct answer

Answer: (d)D.

170240

Why this answer is correct

Shortcut Trick

Winner's share = Total Voters × Valid % × Winning %

Winner's share = 3,20,000 × 95% × 56%

Winner's share = 3,20,000 × (95 / 100) × (56 / 100)

Winner's share = 32 × 95 × 56 = 1,70,240

∴ The correct answer is 1,70,240.

Alternate Method

Given:

⇒ Total Voters = 3,20,000

⇒ Invalid Votes = 5% of Total

⇒ Winner's Share = 56% of Valid Votes

Calculations:

⇒ Total number of votes = 3,20,000

⇒ Number of valid votes = 95% of 3,20,000

⇒ Valid votes = (95 / 100) × 3,20,000 = 3,04,000

⇒ Winning candidate's votes = 56% of Valid votes

⇒ Winner's votes = (56 / 100) × 3,04,000

⇒ Winner's votes = 56 × 3,040 = 1,70,240

∴ The correct answer is 1,70,240.

Additional Information

Valid and Invalid Votes

Valid votes are those used to determine the winner and loser. Total Votes = Valid Votes + Invalid Votes.

Victory Margin

The margin of victory is the difference between the votes of the winner and the runner-up. Margin = (Winner's % − Loser's %) × Valid Votes.

Successive Percentages

When multiple percentage conditions apply (like invalid then winning share), the final value is found by multiplying successive factors: Final = Initial × (1 − r1/100) × (r2/100).

  3. COption (c)

    90%

  4. DOption (d)

    80%

View answer & explanation

Correct answer

Answer: (c)C.

90%

Why this answer is correct

GIVEN:

Percentage of different types of expenditure in 2020 and 2021

CONCEPT USED:

100% represents Total expenditure in both cases respectively

CALCULATION:

Here, the Percentage of expenditure on Education in 2020 = 25%

⇒ Total expenditure in 2020 = Rs960000

Hence,

100% = 960000

25% = 240000

Now, the Percentage of expenditure  on Food in 2021 = 20%

⇒Total expenditure in 2021 = Rs1080000

Hence,

100% = 1080000

20% =  216000

Now, we have to find the percentage of expenditure on food in 2021 to the expenditure on education in 2020

⇒ (216000/240000) × 100 = 90%

Hence, the required percentage is 90%.

Correct answer

Answer: (a)A.

6\sqrt {6}

Why this answer is correct

FORMULA USED:

(a+b)2=a2+b2+2ab( a +b )^2 = a^2 + b^2 + 2ab 

CALCULATION:

Here, 2+3+\sqrt{2 + \sqrt3} + 2−3\sqrt{2 - \sqrt3}         Where,  a = 2+3\sqrt{2 +\sqrt3} , b = 2−3\sqrt{2 - \sqrt3} 

⇒ Hence, on squaring we get,

⇒ (2+3+2−3)2( \sqrt{2 +\sqrt3} + \sqrt{2 - \sqrt3})^2  =  (2+3)2+(2−3)2( \sqrt{2 + \sqrt3})^2 + (\sqrt{2 - \sqrt3})^2 + 2 × (2+3)(2−3)( \sqrt{2 + \sqrt3}) ( \sqrt{2 - \sqrt3}) = 2+32 + \sqrt3   +  2−32 - \sqrt3 + 2 × (1)  = 6

⇒ (2+3+2−3)2( \sqrt{2 +\sqrt3} + \sqrt{2 - \sqrt3})^2  = 6

⇒ (2+3+2−3)( \sqrt{2 +\sqrt3} + \sqrt{2 - \sqrt3})   = 6\sqrt {6}

Hence, the required value is 6\sqrt {6}.

Correct answer

Answer: (c)C.

86

Why this answer is correct

Shortcut Trick

Identify prime numbers on a dice: 2, 3, and 5.

Sum their corresponding frequencies from the table.

Total frequency of prime numbers = 43 + 33 + 10 = 86.

∴ The correct answer is 86.

Alternate Method

Given Data from Frequency Table:

Frequency of Outcome 1 = 23

Frequency of Outcome 2 = 43

Frequency of Outcome 3 = 33

Frequency of Outcome 4 = 13

Frequency of Outcome 5 = 10

Frequency of Outcome 6 = 28

Total Throws = 150

Prime numbers in the set {1, 2, 3, 4, 5, 6}:

⇒ 1 is neither prime nor composite.

⇒ 2 is a prime number.

⇒ 3 is a prime number.

⇒ 4 is a composite number (2 × 2).

⇒ 5 is a prime number.

⇒ 6 is a composite number (2 × 3).

Calculation for prime number frequency:

⇒ Total prime frequency = Freq(2) + Freq(3) + Freq(5)

⇒ Total prime frequency = 43 + 33 + 10

⇒ Total prime frequency = 86

∴ The correct answer is 86.

Additional Information

Definition of Prime Numbers

A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. The first few are 2, 3, 5, 7, 11...

Special Case of 1

The number 1 is not considered a prime number because it does not have exactly two distinct divisors; it only has one divisor (1).

Probability of Prime Numbers

The experimental probability P(Prime) = (Total frequency of prime outcomes) ÷ (Total number of trials). In this case, P(Prime) = 86 ÷ 150 = 43/75.

  4. DOption (d)

    164485

View answer & explanation

Correct answer

Answer: (b)B.

185625

Why this answer is correct

CONCEPT USED:

Divisibility by 5  = If the last digit of a number is either 0 or 5, then that number is divisible by 5

Divisibility by 11= If the difference of the sum of alternative digits of a number is divisible by 11, then that number is divisible by 11

CALCULATION:

As 55 = ( 5 × 11) Hence, any number will be divisible by 55 only when it is divisible by 5 and 11 both

As, in all the options given here, the last digit is 5. Hence, all the numbers in the options are divisible by 5.

So, the numbers are to be divisible by 55. We have to only check the divisibility of 11.

Considering option (1), we have

⇒ 178765 = ( 1 + 8 + 6) - ( 7 +7 +5) =  ( 15 - 19) = -4, which is not divisible by 11.Hence, 178765 is also not divisible by 11

considering option (2), we have

⇒ 185625 = ( 1 + 5 + 2 ) - ( 8 + 6 + 5) = ( 8 - 19 ) = -11, which is divisible by 11.Hence, 185625 is divisible by 11

Considering option (3), we have

⇒ 171125 = ( 1 + 1 +2 ) - ( 7 + 1 + 5 )= ( 4 - 13) = -9, which is not divisible by 11. Hence, 171125 is also not divisible by 11

Considering option (4), we have

⇒ 164485 = ( 1 + 4 + 8 ) -( 6 + 4 + 5 ) =  ( 13 - 15 ) = -2, which is not divisible by 11. Hence,164485 is also not divisible.

 As the number 185625 is divisible by 5 and 11 both. Hence, it is divisible by 55.

Hence, 185625 is divisible by 55.

CALCULATION:

Here, we have 99 × 99 -1

Which can be rewritten as 992−1299^2 -1^2 in the form of (a2−b2)( a^2 - b^2)

⇒ Where, a = 99 and b = 1

⇒ (992−12)( 99 ^2 - 1^2) = ( 99 +1 )( 99 -1) = 100 × 98 = 9800

Hence, the required value is 9800.

View answer & explanation

Correct answer

Answer: (a)A.

48

Why this answer is correct

GIVEN:

Speed = 40km/h

Returning speed = 60 km/h

FORMULA USED:

Distance = Speed × Time 

Average speed = Total Distance travelled/Total time taken

CALCULATION:

Let the total distance travelled by 2d

Here, Speed = 40 km/h, Distance while going = d

⇒ Time = Distance/Speed = d/40 h

Now, returning speed = 60 km/h, Distance while returning = d

⇒ Time = Distance/ Speed = d/60 h

⇒ Total Distance traveled = 2d 

⇒ Total Time taken = ( d/40 + d/60) h = d/24 h

Now, Average = Total Distance / Total time = 2d ÷ (d/24) = 48 km/h.

Hence, the Average is 48 km/h.

Correct answer

Answer: (b)B.

45000

Why this answer is correct

GIVEN:

Present population = 54450

Rate increment per year = 10%

FORMULA USED:

Present population = Initial population × (100+R100)t( \frac{100 + R}{100}) ^t

Where,  R = Rate of increment , t = time in years

CALCULATION:

Here, we have Present population = 54450 , Time = 2 years ,   R = 10%

⇒ Present population = Initial population × (100+R100)t(\frac{100 +R}{100}) ^t

⇒ 54450 = Initial population × (100+10100)2( \frac{100 + 10}{100}) ^2

⇒ 54450 = Initial population × 110/100 × 110/100 

⇒ Initial population = 54450 × 10/11 × 10/11 = 45000

Hence, the population two years ago was 45000.

Answer: (d)D.

59318

Why this answer is correct

GIVEN:

p = 38

FORMULA USED:

(a+b)3=a3+b3+3a2b+3ab2( a + b) ^3 = a^3 +b^3 + 3a^2b + 3ab^2

CALCULATION:

Here, we have p( p2p^2 +3p +3) 

⇒ p ( p2p^2 +3p +3) = p3+3p2+3pp^3 + 3p^2 +3p              ...................(1)

Now add 1 in equation (1). But if we add 1 extra from our side so to balance it, we have to subtract 1 as well

⇒ p3+3p2+3p+1−1p^3 + 3p^2 +3 p +1 - 1 

Now, this can be rearranged as  (p3+1+3p2+3p)−1(p^3 +1 +3p^2 +3p) -1

Now, the above equation is in the form of a3+b3+3a2b+3ab2a^3 +b^3 +3a^2b + 3ab^2  where a= p and b= 1

⇒ (p+1)3−1( p +1)^3 -1

Now, the value of p is given as p =38

⇒ (p+1)3−1( p +1)^3 -1 = (38+1)3−1( 38 +1)^3 -1 = 393−139^3 -1 = ( 59319 -1) = 59318

Hence, the required value is 59318.

∠B=52.4∘\angle B = 52.4^\circ ∠C=45.5∘\angle C = 45.5 ^\circ ∠A=82.5∘\angle A = 82.5^\circ

Now, considering triangle DEF, we have

  DE = 4 cm , EF = 5 cm , DF = 3.6cm

⇒ Since, all the corresponding sides are equal. Hence, triangle DEF is congruent to triangle ABC by SSS ( Side -Side -Side)

Now, considering triangle GHI we have

  

  Now, here we have HI = 5cm , ∠H=52.4∘,∠I=45.5∘\angle H = 52.4^\circ , \angle I = 45.5^\circ

Since, two angles and one side included between them of triangle GHI is equivalent to the two angles and one side included of the triangle ABC

Hence, triangle GHI is congruent to triangle ABC by ASA( Angle- Side - Angle)

Now, considering JKL, we have,

Now, here we have JK= 3.6 cm, JL = 4 cm ∠J=52.4∘\angle J = 52.4^\circ Since, angle included between the two sides of triangle JKL is not equal to the angle included between the two sides of triangle ABC Hence, triangle JKL does not follow the property of SAS (Side - Angle - Side ) So, JKL is not congruent to ABC

Question 64

A person borrowed a sum of ₹8,000 at an interest rate of 10% p.a., compounded semi- annually. What is the compound interest for a period of 1 year?

  1. AOption (a)

    ₹820

  2. BOption (b)

    ₹1,600

  3. COption (c)

    ₹1,680

  4. DOption (d)

    ₹800

View answer & explanation

Correct answer

Answer: (a)A.

₹820

Why this answer is correct

Shortcut Trick

For semi-annual compounding, the rate is halved and the number of periods is doubled.

Rate (r) = 10% ÷ 2 = 5% per half-year | Periods (n) = 1 year × 2 = 2.

Effective Rate for 2 periods of 5% = 5 + 5 + (5 × 5)/100 = 10.25%.

Compound Interest (CI) = 8000 × 10.25% = ₹820.

∴ The correct answer is ₹820.

Alternate Method

Given: Principal (P) = ₹8,000, Rate (R) = 10% p.a., Time (T) = 1 year.

Formula Used: Amount (A) = P(1 + r/100)n; CI = A − P.

⇒ Since interest is compounded semi-annually:

⇒ Rate (r) = 10% ÷ 2 = 5% per half-year.

⇒ Number of periods (n) = 1 × 2 = 2 half-years.

⇒ A = 8000 × (1 + 5/100)2

⇒ A = 8000 × (21/20) × (21/20)

⇒ A = 20 × 441 = 8820

⇒ Compound Interest (CI) = 8820 − 8000 = 820.

Question 65

Sudhir claimed to sell his items at only 8% above the cost of production, but used a weight that had 750 grams written on it, though it actually weighed 720 grams. What was the actual profit percentage earned by Sudhir?

  1. AOption (a)

    12.6%

  2. BOption (b)

    12.25%

  3. COption (c)

    12.5%

  4. DOption (d)

    12.75%

View answer & explanation

Correct answer

Answer: (c)C.

12.5%

Why this answer is correct

FORMULA USED:

Profit = S.P. - C.P.

Profit% = (Profit/C.P.) × 100

Where, S.P = Selling price, C.P. = Cost price 

CALCULATION:

Sudhir sells his items at an 8% profit 

⇒ Profit% =( Profit /C.P.) × 100

⇒ 8 = (S.P. - C.P.)/C.P. × 100 

⇒ 108 C.P. = 100 S.P.  or S.P.= 1.08 C.P.

But when Sudhir uses weights that measure only 720 grams while he claims to measure 750 grams

Hence, C.P. of  720 grams = (720/750) × Original C.P. = 0.96 of original C.P.

So, he is selling goods worth 0.96 at 1.08 C.P. 

⇒ Hence, he makes a profit of ( 1.08 - 0.96)  = 0.12 C.P. on his cost of 0.96 C.P.

⇒ Profit% = ( 0.12/ 0.96) × 100 = 12.5

Hence, actual Profit percentage earned by Sudhir is 12.5%.

    B2

  4. DOption (d)

    B4

View answer & explanation

Correct answer

Answer: (a)A.

B1

Why this answer is correct

FORMULA USED:

Average = Sum of values/No. of values

CALCULATION:

Average of these four  brands in the year 2016-2017

⇒ Average = ( 5 + 4 + 10 + 8) /4 = 6.75

Since, B3 = 10 and B4 = 8 has more values than the average 

Hence, According to the given Question, values more than average will get a star 

⇒ B3 and B4 get a star.

Average of these four brands in the year 2017-2018

⇒ Average = ( 7 + 9 + 11 + 10 ) /4 = 9.25

Since, B3 = 11 and B4 = 10 

Hence, B3 and B4 again gets a star

Average of these four brands in the year 2018-2019

⇒ Average = (12 + 11 + 10 +9)/4 = 42/4 = 10.5

Since, B1 = 12 and B2 = 11 

⇒ B1 and B2 gets a star

Average of these four brands in the year 2019-2020

⇒ Average = ( 14 + 15 + 12 + 15)/4 = 14

Since, B2 = 15 and B4 = 15

⇒ B2 and B4 gets a star

⇒ Total star gets by B1 = 1

⇒ Total star gets by B2 = 2

⇒ Total star gets by B3 = 2

⇒ Total star gets by B4 = 3

So, B1 gets a minimum number of stars

Hence, B1 gets a minimum number of stars from 2016-2020.

Correct answer

Answer: (a)A.

116.67 gm

Why this answer is correct

GIVEN:

Copper : Bronze = 3 :4 

Total alloy = 350 gram

Final ratio after the addition of quantity in Copper = 4:3

CALCULATION:

Here, Copper : Bronze = 3:4 

Let, the Copper and Bronze be 3x and 4x  and Total alloy given = 350 gram

⇒ (3x + 4x) = 350

⇒ 7x = 350 ⇔ x = 50 gram

⇒ Copper = 3x = ( 3 × 50) = 150 gram , Bronze = 4x = ( 4 × 50 ) = 200 gram

Now, let the quantity added to the copper be y

 According to the given Question,

⇒ (150 + y) : 200 = 4 :3 

⇒ 800 = 450 + 3y

View answer & explanation

Correct answer

Answer: (b)B.

6126\frac{1}{2} days

Why this answer is correct

GIVEN:

A completes the work = 5 days

B completes the work = 10 days

A and B work alternately

CALCULATION:

Complete the work in 5 days

⇒ A's 1 day work = 1/5 

B complete the work in 10 days

⇒ B's 1 day work = 1/10

⇒ ( A + B )'s work in 2 days =  ( 1/5 + 1/10)= 3/10 

In 3 pairs of 2 days they will complete 3/10 × 3 = 9/10

⇒ Hence, after 3 × 2 = 6 days, 1 - 9/10 = 1/10 work is left which will be done by A alone.

⇒ A  does 1 work in 5 days 

⇒ A does 1/10 work in 5 × 1/10 = 1/2 days

⇒ Total number of days =  6 + 1/2 = 6 121\over 2days

Hence, they will complete the work in 6 121\over 2 days.
