Thank you..

Tips-
The ESE interview will most probably start with whatever is mentioned in the DAF. So, be absolutely honest with what you are going to fill in.
Also, since i had already been undergoing training at BARC, i wanted the panel to ask me questions based on that. So, I mentioned BARC right at the beginning of the interview and it really helped. In the ESE interview, the panel might not ask you your favorite subjects, so be prepared with only the fundamentals of all the subjects, especially Manufacturing.

At the end, just revise ur prelims notes once... and stay relaxed..!!

400 Placement Aptitude questions

 

1. The cost price of 10 articles is equal to the selling price of 9 articles. find the profit percent.

a. 101/9 %

b. 100/9 %

c. 102/9 %

d. 103/9 %

Ans: 100/9 %

Let Cost Price be x and selling price be y

Then given that cost price of 10 articles is equal to the selling price of 9 articles

That means 10x=9y

Y= 10x/9

Profit percent = (( selling price – cost price )/cost price ) * 100 = 100/9 %


2. The ratio of radii of two right circular cylinders is 6:7 and their heights are in the ratio 5:9. The ratio of their respective curved surface areas is

a. 14:15

b. 17:19

c. 23:29

d. 10:21

Ans: 10 : 21

Curved surface area of a cylinder = 2 * Pi * r * h

Ratio = (6/7) * (5/9) = 10:21


3. In how many ways can the 7 letters A,B,C,D,E,F and G be arranged so that C and E never together.

a. 5040

b. 6480

c. 3600

d. 1440

Ans: 3600

C and E never together = Total arrangements – C and E together

Total arrangements are 7!

C and E together = pack c and e into one unit + 5 other alphabets = 6! 2! ( 2! Is two arrange c and e

internally)

C and E never together = Total arrangements – C and E together = 7! – 6! 2! = 3600


4. How many numbers are there in all from 4000 to 4999 (both 4000 and 4999 included) having at least one of their digits repeated?

a. 356

b. 216

c. 496

d. 504

Ans: 496

Atleast one of their digits repeated = Total numbers – None of the digits repeated

Total numbers from 4000 to 4999 = 1000

None of the digits repeated = _ _ _ _5

There are total 4 places

1st place is filled with 4 only. So only one choice

2nd place is filled with any 9 digits except 4 as we have used 4 in 1st place. So 9 choices

Similarly 3rd place is filled with any 8 digits. So we have 8 choices

4th place is filled with any 7 digits. So we have 7 choices.

So total arrangements = 1 * 9 * 8 * 7 = 504

Ans= 1000 – 504 = 496

c. 320 km

d. 420 km

Ans: 324 km

Let Dhruv takes t hours then Naksh takes t-3 hours

Because distance is same in both cases

So 36 * t = 54 (t-3)

t=9

ans: 36 * 9 = 324 km


12. The radius of wheel of axis's car is 50 cm. What is the distance that the car would cover in 14

revolutions?

a. 11 m

b. 22 m

c. 33 m

d. 44 m

Ans: 44 m

a. 2 days

b. 3 days

c. 4 days

d. 5 days

Ans: 3 days

P can do in 5* 8 hours= 40 hours

Q can do in = 24 hours

Working together in one hour = (1/40) + (1/24) = 1/15

Total work can be finished in 15 hours

They 5 hours a day so total number of days = 15/5 = 3 days7


14. Libra had three diamonds weighing equal. One of the diamond fell and broke into 4 equal pieces weighing 20 gm each. what was the total weight of the three diamonds?

Ans: (a) let’s say original ratio is x:y

(x+5)/(y+6) = 5/6

Then x/y = 5/6

17. Rohit and Rahul start from the same point and move away from each other at right angle. After 4 hours they are 80 km apart. if the speed of Rohit is 4 kmph more than Rahul. what is the speed of Rohit?
