### Quantitative Analysis

**If the average of 5 consecutive even numbers is 10, find the middle number?**- 4
- 8
- 2
- 10

**Answer:****10****Explanation:**Let the five consecutive even numbers be

x-4, x-2, x, x+2, x+4Average of these = ((x-4)+(x-2)+(x)+(x+2)+(x+4))/5 = x

Given average = 10Therefore x = 10

**Two numbers are in the ratio of 2:9. If their H. C. F. is 19, numbers are:**- 6, 27
- 8, 36
- 38, 171
- 20, 90

**Answer:****38, 171****Explanation:**Let the numbers be 2X and 9X

Then their H.C.F. is X, so X = 19

=> Numbers are (2×19 and 9×19) i.e. 38 and 171**Three friends started running together on a circular track at 8:00:00 am. Time taken by them to complete one round of the track is 15 min, 20 min, 30 min respectively. If they run continuously without any halts, then at what time will they meet again at the starting point for the fourth time ?**- 8:30:00 am
- 9:00:00 pm
- 12:00:00 pm
- 12:00:00 am

**Answer:****12:00:00 pm****Explanation:**LCM (15, 20, 30) = 60

=> They meet at the starting point after every 60 min, i.e., after every 1 hour.

Therefore, they will meet at the starting point for the fourth time after 4 hours, i.e., at 12:00:00 pm.**Two friends A and B were employed to do work. The initial deadline was fixed at 24 days. Both started working together but after 20 days, A left the work and the whole work took 30 days to complete. In how much time can B alone can do the work?**- 40
- 50
- 60
- 70

**Answer:****60****Explanation:**Let the total work be 24 units. It is given that A and B together can do the work in 24 days.

=> Combined efficiency of A and B = 24/24 = 1 unit / day

=> Work done in 20 days = 20 units

=> Work left = 24 – 20 = 4 units

Now, this remaining 4 units of work was done by B alone in 10 days.

=> Efficiency of B = 4/10 = 0.4

Therefore, time required by B alone to do the work = 24/0.4 = 60 days**Two pipes A and B attached to a swimming pool can fill the pool in 20 minutes and 30 minutes respectively working alone. Both were opened together but due to malfunctioning of the motor of pipe A, it had to be shut down after two minutes but B continued to work till the swimming pool was filled completely. Find the total time taken to fill the pool.**- 20
- 22
- 25
- 27

**Answer:****27****Explanation:**Let the capacity of the pool be LCM(20, 30) = 60 units.

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

=> Efficiency of pipe B = 60 / 30 = 2 units / minute

=> Combined efficiency of pipe A and pipe B = 5 units / minute

Now, the pool is filled with the efficiency of 5 units / minute for two minutes.

=> Pool filled in two minutes = 10 units

=> Pool still empty = 60 – 10 = 50 units

This 50 units is filled by B alone.

=> Time required to fill these 50 units = 50 / 2 = 25 minutes

Therefore, total time required to fill the pool = 2 + 25 = 27 minutes**Samuel covers the distance from his home to his office at a speed of 25 km/hr and comes back at a speed of 4 km/hr. He completes the whole journey within 5 hours 48 minutes. Find out the distance from his home to office:**- 20 km
- 18 km
- 15 km
- 25 km

**Answer:****20 km****Explanation:**Let the speed of travelling to office and back to home be x and y respectively.

So, his average speed is = 2xy / (x+y) = (2 × 25 × 4) / (25 + 4) = 200/29 km/hr

He covers the whole journey in 5 hours 48 minutes = 5=> = 29/5 hrs

Therefore, total distance covered = (200/29 × 29/5) = 40 km

So, the distance from his home to office = 40/2 = 20 km**A boatman takes 3 hours 45 minutes to travel 15 km downstream and takes 2 hours 30 minutes to travel 5 km upstream of a river. What is the speed of the stream of the river in km/h?**- 2 km/h
- 1 km/h
- 6 km/h
- 4 km/h

**Answer:****1 km/h****Explanation:**Downstream:

Time taken = 3 + 45/60 = 3 + 3/4 = 15/4 h.

Distance covered = 15 km.

Downstream Speed = 15 / (15/4) = 4 km/h.

Upstream:

Time taken = 2 + 30/60 = 2 + 1/2 = 5/2 h.

Distance covered = 5 km.

Upstream Speed = 5 / (5/2) = 2 km/h.

We know, speed of stream

= 1/2 (Downstream Speed – Upstream Speed)

= 1/2 (4-2) = 1 km/h.**John earns 33.33% more than Peter. By what percentage is Peter’s earning less than that of John’s?**- 22 %
- 25 %
- 26 %
- 23 %

**Answer:****25 %****Explanation:**Let John’s income be j and Peter’s income be p. Then,

j = p + p × 33.33% = p + p × 100?3 % = p + p × 1/3 = 4p/3

=> p = 3j/4 = (4 – 1)j/4 = j – j/4 = j – j × 1/4 = j – j × 100?4 % = j – j × 25%.

Therefore, Peter’s earning is less than John’s earning by 25%.**Present age of Vinod and Ashok are in ratio of 3:4 respectively. After 5 years, the ratio of their ages becomes 7:9 respectively. What is Ashok’s present age is ?**- 40 years
- 28 years
- 32 years
- 36 years

**Answer:****40 years****Explanation:**Let the present age of Vinod and Ashok be 3x years and 4x years respectively.

Then (3x+5) / (4x+5) = 7 / 9=> 9(3x + 5) = 7(4x + 5)

=> 27x + 45 = 28x + 35

=> x = 10

=> Ashok’s present age = 4x = 40 years**Sum of 4 childeren born at interval of 4 years is 36. What is the age of youngest child?**- 2 years
- 3 years
- 4 years
- 5 years

**Answer:****3 years****Explanation:**Let the ages of children be x, (x+4),

(x+8) and (x+12) years.Then x + x + 4 + x + 8 + x +12 = 36

4x + 24 = 36

4x = 12

x = 3

Age of the youngest child = x = 3 years

**After several defeats in wars, Robert Bruce went in exile and wanted to commit suicide. Just before committing suicide, he came across a spider attempting tirelessly to have its net. Time and again, the spider failed but that did not deter it to refrain from making attempts. Such attempts by the spider made Bruce curious. Thus, Bruce started observing the near-impossible goal of the spider to have the net. Ultimately, the spider succeeded in having its net despite several failures.
