### Quantitative Analysis

**If the sum of two numbers is 13 and the sum of their square is 85. Find the numbers?**.- 6, 7
- 5, 8
- 4, 9
- 3, 10

**Answer:****6, 7****Explanation:**Let the numbers be x and 13-x

Then x^{2}+ (13 – x)^{2}= 85

=> x^{2}+ 169 + x^{2}– 26x = 85

=> 2 x^{2}– 26x + 84 = 0

=> x^{2}– 13x + 42 = 0

=> (x-6)(x-7)=0Hence numbers are 6 & 7

**HCF of two numbers is 11 and their LCM is 385. If the numbers do not differ by more than 50, what is the sum of the two numbers ?**- 132
- 35
- 12
- 36

**Answer:****132****Explanation:**Product of numbers = LCM x HCF = 11 x 385 = 4235

Let the numbers be of the form 11m and 11n, such that ‘m’ and ‘n’ are co-primes.

=> 11m x 11n = 4235

=> m x n = 35

=> (m, n) can be either of (1, 35), (35, 1), (5, 7), (7, 5).

=> The numbers can be (11, 385), (385, 11), (55, 77), (77, 55).

But it is given that the numbers cannot differ by more than 50.

Hence, the numbers are 55 and 77.

Therefore, sum of the two numbers = 55 + 77 = 132**The LCM of two co-prime numbers is 117. What is the sum of squares of the numbers ?**- 220
- 1530
- 250
- 22

**Answer:****250****Explanation:**117 = 3 x 3 x 13

As the numbers are co-prime, HCF = 1.

So, the numbers have to be 9 and 13.

9^{2}= 81

13^{2}= 169

Therefore, required answer = 250**A and B took a job to be completed in 20 days. They started working together and after 12 days, C joined them and the whole job finished in 15 days. How much time would C require to complete the job if only C was hired?**- 15
- 12
- 10
- 8

**Answer:****12****Explanation:**Let the total job be 20 units. It is given that A and B took the job to be completed in 20 days.

=> Combined efficiency of A and B = 20/20 = 1 unit / day

Now, job done in 12 days = 12 units

=> Job Left = 8 units

Now, this remaining 8 units of job have been done by all A, B and C together.

Let the efficiency of C be ‘x’.

=> Combined efficiency of A, B and C = 1+x units/ day

Now, with this efficiency, the job got completed in 3 more days.

=> Job done in 3 days = 3 x (1+x) = 8 units

=> x = 5/3

Therefore, efficiency of C = x = 5/3 units / day

Hence, time required by C alone to do the job = 20/(5/3) = 12 days**Three pipes A, B and C were opened to fill a cistern. Working alone, A, B and C require 12, 15 and 20 minutes respectively. After 4 minutes of working together, A got blocked and after another 1 minute, B also got blocked. C continued to work till the end and the cistern got completely filled. What is the total time taken to fill the cistern ?**- 6 minutes
- 6 minutes 15 seconds
- 6 minutes 40 seconds
- 6 minutes 50 seconds

**Answer:**

**6 minutes 40 seconds****Explanation:**Let the capacity of the cistern be LCM(12, 15, 20) = 60 units.

=> Efficiency of pipe A = 60 / 12 = 5 units / minute

=> Efficiency of pipe B = 60 / 15 = 4 units / minute

=> Efficiency of pipe C = 60 / 20 = 3 units / minute

=> Combined efficiency of pipe A, pipe B and pipe C = 12 units / minute

Now, the cistern is filled with the efficiency of 12 units / minute for 4 minutes.

=> Pool filled in 4 minutes = 48 units

=> Pool still empty = 60 – 48 = 12 units

Now, A stops working.

=> Combined efficiency of pipe B and pipe C = 7 units / minute

Now, the cistern is filled with the efficiency of 7 units / minute for 1 minute.

=> Pool filled in 1 minute = 7 units

=> Pool still empty = 12 – 7 = 5 units

Now, B also stops working.

These remaining 5 units are filled by C alone.

=> Time required to fill these 5 units = 5 / 3 = 1 minute 40 seconds

Therefore, total time required to fill the pool = 4 minutes + 1 minutes + 1 minute 40 seconds = 6 minutes 40 seconds**If John walks at the speed of 5 km/h, he reaches his office 7 minutes late. However, if he walks at a speed of 6 km/h, he reaches his office 5 minutes early. How far is his office from his home?**- 9
- 8
- 10
- 6

**Answer:****6****Explanation:**Let the distance of John’s office from his home be x.

The time difference when covering the distance x at the two different speeds = 5 – (-7) = 12 min = 1/5 hr

=> x/5 – x/6 = 1/5

=> (6x – 5x)/30 = 1/5

=> x = 6.

So, his office is 6 km far from his home.**A speedboat runs 6 km upstream in a river and comes back to the starting point in 33 minutes. The stream of the river is running at 2 km/hr. What is the speed of speedboat in still water?**- 25 km/h
- 21 km/h
- 26 km/h
- 22 km/h

**Answer:****22 km/h****Explanation:**Let the speed of speedboat in still water be x km/h.

Then, speed downstream = (x + 2) km/h, speed upstream = (x – 2) km/h.

Since it goes 6 km upstream and comes back in 33 minutes, we have

6/(x+2) + 6/(x-2) = 33/60

=> 11x² – 240x – 44 = 0

=> 11x² – 242x + 2x – 44 = 0

=> (x – 22)(11x + 2) = 0

=> x = 22.

Therefore, the required speed = 22 km/h.**Mary’s salary is reduced by 10%. By what percentage must her new salary be increased in order to gain her old salary?**- 137/9 %
- 194/9 %
- 100/9 %
- 110/9 %

**Answer:****100/9 %****Explanation:**

Let her old salary be Rs 100. Then, her new salary = 100 – 10 = Rs 90.

So, to gain her old salary, her new salary must be increased by Rs 10.

Therefore, the required percentage = (10?90) × 100% = 100/9 %.**At present, the ratio between the ages of Ram and Shyam is 6:5 respectively. After 7 years, Shyam’s age will be 32 years. What is the present age of Ram?**- 32
- 40
- 30
- 36

**Answer:****30****Explanation:**Let the present age of Ram and Shyam be 6x years and 5x years respectively.

Then 5x + 7 = 32

=> 5x = 25

=> x = 5

=> Present age of Ram = 6x = 30 years**A is 5 years older than B who is thrice as old as C. If the total of ages of A, B and C is 40, then how old is C ?**- 6
- 7
- 5
- 8

**Answer:****5****Explanation:**Let C’s age be x years then B’s age be 3x

years and A’s age be (3x+5) yearsTherefore x + 3x + (3x + 5) = 40

7x + 5 = 40

7x = 35

x = 5
