Given:

Saral alone can complete the work in 15 days.

Kanika alone can complete the work in 18 days.

Concept Used:

Total units of work = L.C.M of total required days to complete the work

Efficiency = Total units of work/Total number of days.

Solution:

Total units of work = L.C.M of total required days to complete the work

⇒ Total units of work = 15 & 18

⇒ Total units of work = 90 units

Efficiency = Total units of work/Total number of days.

Efficiency of Saral = 90/15 = 6 units/day

Efficiency of Kanika = 90/18 = 5 units/day

On the First day, Saral will work, 

⇒ Work done on the First day = 6 units

On the Second day, Kanika will work, 

⇒ Work done on the Second day = 5 units

Work done in 2 days = 5 + 6 = 11 units.

Multiplying by 8, we get, so we will get units of work near to 90, 

⇒ Work done in 2 × 8 = 16 days is 11 × 8 = 88 units of work,

Remaining units of work = 90 - 88 = 2 units 

Now on the 17th day Saral will work,

⇒ 2/6 = 1/3 day to complete 2 units of work 

Total number days = 16 + 1/3 = $16\frac{1}{3}$ days

∴ Total number of days required is  $16\frac{1}{3}$ days

Given:

a – b = 9

Calculation:

⇒ a = b + 9                 → (1)

⇒ (a – 18)³ – (b – 9)³

⇒ Putting the value from (1), we get

⇒ (b + 9 – 18)³ – (b – 9)³

⇒ (b – 9)³ – (b – 9)³ = 0

Therefore, the value of expression is 0.

Given:

Height of cylinder = 14 cm

CSA of cylinder = 88 cm²

Concept Used:

Curved Surface Area of cylinder = $2\pi rh$

Calculation:

⇒ According to the question,

⇒ 2 × $\frac{22}{7}$ × r × 14 = 88

⇒ 44 × 14 × r = 88 × 7

⇒ r = $\frac{88\times 7}{44\times 14}$ = 1 cm

⇒ Diameter of base = 2r = 2 × 1 = 2 cm

Therefore, the diameter of the base of a cylinder is 2 cm.

Shortcut Trick

The direct relationship between the area of a sector, its arc length (l), and its radius (r) is given by: Area = (1/2) × l × r

Here, Area = 385 cm² and the radius (r) = d/2 = 35/2 cm.

Substituting the known values into the formula:

385 = (1/2) × l × (35/2) ⇒ l = (385 × 4) ÷ 35 = 44 cm

∴ The correct answer is 44 cm.

Alternate Method

Given:

Diameter of the circle (d) = 35 cm

Area of the sector = 385 cm²

Formula Used:

Radius (r) = d ÷ 2

Area of a sector = (θ ÷ 360°) × πr²

Length of an arc (l) = (θ ÷ 360°) × 2πr

Area = 385 cm² r = 17.5 cm r = 17.5 cm Arc length (l) = ?

Calculations:

⇒ Radius (r) = 35/2 = 17.5 cm

⇒ Area of the sector = (θ ÷ 360°) × πr² = 385

⇒ (θ ÷ 360°) × (22/7) × (35/2) × (35/2) = 385

⇒ (θ ÷ 360°) × (22/7) × (1225/4) = 385

⇒ (θ ÷ 360°) × 962.5 = 385

⇒ (θ ÷ 360°) = 385 ÷ 962.5 = 2/5

Now, calculate the length of the arc (l):

⇒ l = (θ ÷ 360°) × 2πr

⇒ l = (2/5) × 2 × (22/7) × (35/2)

⇒ l = (2/5) × 110

⇒ l = 44 cm

∴ The correct answer is 44 cm.

The area of a circle's sector can be established using its central angle θ: Area = (θ ÷ 360°) × πr², or purely by using its continuous arc length: Area = (1/2) × l × r.

Length of an Arc

The arc length represents the distance over the curved part of a sector. It scales proportionally with the whole circumference: l = (θ ÷ 360°) × 2πr.

Perimeter of a Sector

The overall boundary of a particular sector incorporates the arc length alongside the two uniform radii: Perimeter = l + 2r.

Given:

Selling price of each printer = Rs 12,000

Gain % = 20%

Loss % = 20%

Concept Used:

CP = \(\frac{100}{100+Profit%}\times SP\)

CP = \(\frac{100}{100-Loss%}\times SP\)

Loss% = $\frac{Loss}{CP}\times 100$

Calculation:

⇒ Printer sold at 20% gain,

⇒ CP of a printer = $\frac{100}{100+20}\times 12000=10000$ Rs

⇒ Printer sold at 20% loss,

⇒ CP of a printer = $\frac{100}{100-20}\times 12000=\frac{100}{80}\times 12000=15000$ Rs

⇒ Total CP of both the printers = 10000 + 15000 = Rs 25,000

⇒ Total SP of both the printers = 12000 + 12000 = Rs 24,000

⇒ Loss = 25000 – 24000 = Rs 1000

⇒ Loss % = $\frac{1000}{25000}\times 100$ = 4%

Therefore, in the entire transaction, there is a loss of 4%.

Given:

Principal Amount = Rs 7,200

Time = 3 years

Amount = Rs 9,576

Concept Used:

Simple Interest = P × R × T / 100

Calculation:

⇒ Amount = Principal Amount + SI

⇒ 9576 = 7200 + $\frac{7200\times R\times 3}{100}$

⇒ 216 × R = 9576 – 7200 = 2376

⇒ R = 2376 / 216

⇒ R = 11%

Therefore, the rate of interest is 11%.

Shortcut Trick

Use the Successive Percentage multiplier method.

Final Population = 80,00,000 × (108/100) × (65/100) × (165/100)

Final Population = 80,00,000 × 1.08 × 0.65 × 1.65

Final Population = 80,00,000 × 1.1583 = 92,66,400

∴ The correct answer is 9266400.

Alternate Method

Given:

Initial Population (P) = 80,00,000

Rate of change: R₁ = +8%, R₂ = −35%, R₃ = +65%

Formula Used:

Final Value = P × (1 + R₁/100) × (1 + R₂/100) × (1 + R₃/100)

Calculations:

⇒ Population at end of 2015 = 80,00,000 × (108/100) = 86,40,000

⇒ Population at end of 2016 = 86,40,000 × (65/100) = 56,16,000

⇒ Population at end of 2017 = 56,16,000 × (165/100)

⇒ Population = 56,160 × 165

⇒ Population = 92,66,400

∴ The correct answer is 9266400.

Additional Information

Successive Percentage Change

When a value changes by a% and then b%, the net change is [a + b + (a×b)/100]%.

Population Formula

Population after n years = P × (1 ± R/100)ⁿ if the rate is constant.

Fractional Multipliers

8% increase = 27/25 | 35% decrease = 13/20 | 65% increase = 33/20.

Given:

 

Calculation:

⇒ Based on the marks obtained,

⇒ Highest marks in Maths = 89 = Ankit

⇒ Highest marks in Physics = 88 = Neha

⇒ Highest marks in Chemistry = 81 = Keval

Therefore, the students who got highest marks in Maths, Physics and Chemistry are Ankit, Neha and Keval respectively.

Given:

Discount = 12.5%

Profit Percentage = 20%

Calculation:

⇒ Let the marked price be Rs x and cost price be Rs 100.

⇒ At profit of 20%,

⇒ Selling price = 100 + 20% of 100 = 100 + $\frac{20}{100}$ × 100 = Rs 120

⇒ Discount which is provided on MP = $\frac{12.5}{100}=\frac{1}{8}$

⇒ Marked price = [1 – $\frac{1}{8}$] x = 120

⇒ Marked price = $\frac{8-1}{8}x$ = 120

⇒ Marked price, x = $\frac{120\times 8}{7}$ = 137.143

⇒ Price percentage higher than CP = 137.143 – 100 = 37.143%

Therefore, the price of goods should be 37.143% higher than the cost price to make a profit of 20%.

Given:

HCF of two numbers = 6

Concept Used:

HCF × LCM = Product of two numbers

Calculation:

⇒ As the condition of product of two numbers should be satisfied.

⇒ So, LCM would be the factor of HCF itself.

⇒ For 24, it is the 4th multiple of 6.

⇒ For 48, it is the 8th multiple of 6.

⇒ For 60, it is the 10th multiple of 6.

⇒ For 56, it is not the multiple of 6.

Therefore, from the options above, 56 cannot be the LCM ever.

Given:

Nominal rate of interest = 10% p.a. half-yearly

Concept Used:

Amount = P$\left(1+\frac{r}{100}\right)^n$

Calculation:

⇒ As the interest is half-yearly, n = 2.

⇒ Rate will also be halved, r = 10 / 2 = 5%

⇒ Let the principal amount be Rs 100.

⇒ Amount = 100 × $\left(1+\frac{5}{100}\right)^2$ = 100 × $\frac{105}{100}$ × $\frac{105}{100}$

⇒ Amount = Rs 110.25

⇒ Effective annual rate of interest = 110.25 – 100 = 10.25%

Therefore, the effective annual rate of interest will be 10.25%.

Given:

A can do the work in 4 days

B can do the work in 8 days

Calculation:

According to question,

A's 1 day's work = 1/4

B's 1 day's work = 1/8

A and B works alternatively

So, 2 day's work with alternate work by A and B = 1/4 + 1/8 = 3/8

(A + B)'s 4 days with alternate work = (3/8) × 2 = 6/8

Remaining work = 1 - 6/8 = 1/4

Now, A will complete the remaining work on 5th day 

A's 5th day work = 1/4

Total time taken = 4 + 1 = 5 days

∴ Working alternatively they will complete the work in 5 days.

Given :

(a + b + c) = 17 and (a2 + b2 + c2) = 117

Formula used :

(a + b + c)² = (a2 + b2 + c² + 2ab + 2bc + 2ac)

Calculations:

 (a - b)2 + (b - c)2 + (c - a)2 

=  a² + b² - 2ab + b² + c² - 2bc + c² + a² - 2ac

=  2(a² + b² + c² ) - ( 2ab + 2bc + 2ac )

=  2(117) - {(a + b + c)² - (a2 + b2 + c²)}

=  234 - {(17)² - (117)}

=  234 - {289 - 117}

=  234 - 172

= 62

Hence, The Required value is 62.

Concept used:

Prime number are those numbers Except 1 which are divisible by 1 and itself.

Calculations:

The logic followed here is:

• 47, 27 → 27 is divisible by 3 and 9. So, 27 is not a prime number
• 57, 67 → 57 is divisible by 3 and 19. So, 57 is not a prime number.
• 191, 193 →77 is divisible by 7 and 11.So, 77 is not a prime number.
• 37, 67 → 37 and 67 are prime numbers.

Hence, '37 and 67' is the correct answer.

Given:

$\rm 1+\cot^2 θ=\frac{625}{49}$ 

Formula used:

Cotø = 1/Tanø

Cosø = √(1 - Sin²ø)

Calculations:

According to question,

$1 + cot²\theta$ = 625/49

⇒ 1 + cos²θ/sin²θ = 625/49

⇒ (sin²θ + cos²θ)/sin²θ = (25/7)²

⇒ 1/sin²θ = (25/7)²

⇒ sinθ = 7/25

Therefore, cos θ = √(1 - sin²θ)

⇒ cos θ = √(1 - 49/625)

⇒ cos θ = √(576/625) 

⇒ cos θ = 24/25

So, (sin θ + cos θ)1/2

= √(7/25 + 24/25)

= (√31)/5

Hence, The Required value is $\frac{\sqrt{31}}{5}$.

Given:

Speed of the metro train from A to B = 40 km/hour

Distance between A and B = 30 km

It stops at 5 stations for 5 minutes each.

Formula used:

Speed = Distance/Time

Average Speed = Total Distance/Total Time

Calculation:

According to question,

Time = Distance/ Speed = 30/40 = 3/4 h

⇒ Total time of journey

= 3/4 + 5 minutes × 5

= 3/4 + ( 5 × 5/60)

= 3/4 + 5/12

= 14/12 

= 7/6 hours 

Average Speed = Total Distance/Total Time

= 30/(7/6)

= 180/7

= 25.7 km/h

∴ The Required average speed is 25.7 km/h.

Given : 

Distance between the thief and the policeman = 800 m

Speed of the thief = 9 km/h

Speed of the policeman = 12 km/h

Time = 10 minutes 

Formula used : 

Speed = Distance/Time

Concept used : 

Relative speed = Speed of policeman – Speed of thief

Calculations : 

Relative speed of the thief and the policeman = 12 – 9

= 3 km/h

Now, Relative Distance travelled in 10 minutes = Time × Relative speed = 3 × (5/18) × 10 × 60

⇒ 1/2 km = 500 m

Total remaining distance between thief and police is = 800 - 500 = 300 m

∴ The Required value is 300 m.

Given:

(x - 1) is a factor of (x2 + 6kx - 7)

Concept used:

If  (x - a) is a factor of (mx2 + nx + q), 

then, x = a must satisfy the equation i.e.,

(ma2 + na + q) = 0

Calculations:

According to concept,

x = 1 must satisfy the equation (x2 + 6kx - 7)

So, (x2 + 6kx - 7) = 0

⇒ (1)² + 6k(1) - 7 = 0

⇒ 1 + 6k - 7 = 0

⇒ 6k = 6

⇒ k = 1

Hence, The Required value of k is 1.

Given:

x = 4

Formula Used:

Fourth proportional of a, b, c = (b × c)/a

Calculation:

According to question, we have:

a = 4x + 3 = 4(4) + 3 = 16 + 3 =  19

b = 7x + 2 = 7(4) + 2 = 28 + 2 = 30

c = 9x + 2 = 9(4) + 2 = 36 + 2 = 38

4th proportional of a, b and c i.e., 19, 30 and 38 respectively is

= (30 × 38)/19 = 60

∴ The fourth proportional is 60.

Given:

A cube has the same volume as surface area.

Concept used:

• A cube is a cuboid that has all the sides equal.
• Surface area of a cube of side 'a' = S = 6a²
• The volume of a cube of side 'a' = V = a³

Calculations:

Given that the surface area and volume of a cube are numerically equal.

Surface area = Volume

6a² = a³

6 = a

So the side of the cube is 6 units.

$\therefore$ The Required value of length is 6 units.

Preparing the family tree using the following symbols:

Similarly.

⇒ 336 : ? → (336 ÷ 14) + 6 = 24 + 6 = 30

Hence, the correct answer is option 1).
