AMAT Interview Questions, Process, and Tips

Answer: 450

Explanation:
10 * 150 = 1500

3 * 100 + 5 * 150 = 1050

1500 – 1050 = 450

Ans: 60 kph

Suppose Person meets the train everyday at 3 PM at Station A.

His speed is 12kph.

So normally he reaches 5 km before the meeting point (pt B) at (5/12 hr = 25 min before) 2:35PM.

But if he is late by 30 min, then he will reach that point (pt B) by 3:05 PM.

Train is traveling at its normal speed so it covers the distance of 5 Km in 5 min starting from Station A and reaches the meeting point (pt B) at 3:05 PM.

So speed of the train is 5KM/5min = 60 kph.

= (1 * 5! * 2!) * 3 + ( 2! * 5 ! * 1) * 3 + ( 3! * 5! ) + ( 5! * 3! )

9 sec=4 times
x sec=12 times
x=(9*12)/4=27 sec

The first number is 36

Step-by-step explanation:
let their common factor be ‘x’

hence,

the ratio be 3x/5x

hence, by condition;

(3x-9)/(5x-9)=9/17 ch upu

9(5x-9)=17(3x-9)

45x-81=51x-153

153-81=51x-45x

72=6x

x=72/6

x=12

the first number is 3x=3×12=36

Time taken to fill repaired cistern = 12 mins

In 1 min, pipe will fill = 1/12

Time taken to fill cistern with leak = 12 + 18 = 30 mins

In 1 min, it will fill = 1/30

Consider the leak as an outlet pipe, so

1/30 = 1/12 – [ in 1 min how much the outlet pipe leaks ]

= 1/12 – 1/30

= 5/60 – 2/60 = 3/60 = 1/20

Therefore, it will take 20 mins for the leak to empty the cistern

Explanation:

The number of ways of selecting three men, two women and three children is:

= ⁴C₃ * ⁶C₂ * ⁵C₃
= (4 * 3 * 2)/(3 * 2 * 1) * (6 * 5)/(2 * 1) * (5 * 4 * 3)/(3 * 2 * 1)
= 4 * 15 * 10
= 600 ways.

divide 100 by 7, and you get 14.28. (Obviously you aren’t talking about decimals here) and so 14 numbers can be divisible by 7 up to 100.

The answer is 14.
