Deloitte Aptitude Questions and Answers - Question 3

M and N’s salaries together amount to Rs. 2,000. M spends 95% of his salary and N spends 85% of his. If now their savings are the same, what is N’s salary?

Detailed Solution for Deloitte Aptitude Questions and Answers - Question 3

Let's assume M's salary is x and N's salary is y.

According to the given information, we can form the following equations:

M + N = 2000 (Equation 1) - their salaries together amount to Rs. 2000

M - 0.95M = N - 0.85N (Equation 2) - their savings are the same

Simplifying Equation 2, we get:

0.05M = 0.15N

Dividing both sides by 0.05, we get:

M = 3N (Equation 3)

Substituting Equation 3 into Equation 1, we get:

3N + N = 2000

Combining like terms, we get:

4N = 2000

Dividing both sides by 4, we get:

N = 500

Therefore, N's salary is Rs. 500.

Hence, the correct answer is option A: Rs. 500.

Deloitte Aptitude Questions and Answers - Question 4

In a horse racing, there are three horses, P, Q, and R. The Payoffs at P is 3: 7, at Q, is 4: 9, at R, is 5: 11. Salman bets Rs. 693 on a horse which would fetch the maximum amount. Luckily his horse has won. Then what is the total amount won by him?

Detailed Solution for Deloitte Aptitude Questions and Answers - Question 5

If Salman bets on horse P: 693*3/7 = 297
If he bets on horse Q: 693*4/9 = 308
If he bets on horse R: 693*5/11 = 315
Hence, Salman bets on horse R and he wins 315
Total = 693+315 = 1008

Two pipes P and Q can fill a tank in 10 hours and 15 hours respectively while a third pipe R can empty the full tank in 20 hours. All the pipes are opened for 5 hours and then R is closed. Find the time in which the tank is full?

Detailed Solution for Deloitte Aptitude Questions and Answers - Question 6

(1/10 + 1/15 – 1/20)*5 + (1/10 + 1/15)*T = 1.
We will get Time = 2.5 hrs
Therefore, the total time = 5 + 2.5 = 7.5 hrs

Deloitte Aptitude Questions and Answers - Question 7

Two pipes M and N can fill a tank in 8 minutes and 12 minutes respectively. If both the pipes are opened simultaneously, after what time should N be closed so that the tank is full in 6 minutes?

Detailed Solution for Deloitte Aptitude Questions and Answers - Question 7

Let us assume that after x minutes pipe N is closed
(1/8 + 1/12)*x + (1/8)*(6 -x) = 1
Therefore, x = 3 minutes

Deloitte Aptitude Questions and Answers - Question 8

Two taps can separately fill the tank in 10 min and 15 min respectively. They fill the tank in 12 minutes when a third pipe which empties the tank is also opened. What is the time taken by the third pipe to empty the whole tank?

Detailed Solution for Deloitte Aptitude Questions and Answers - Question 9

Let us assume the tank full in x minutes
Then P and Q opened for x minutes and R for 6 minutes.
(1/36 + 1/45)*x – (1/30)*6 = 1
(1/20)*x = 6/5
By solving x = 24
Therefore, the tank will be full in 24 mins

Deloitte Aptitude Questions and Answers - Question 10

Pipes M and N can fill a cistern in 15 hours together. But if these pipes operate separately M takes 40 hours less than N to fill the tank. In how many hours the pipe M will fill the cistern working alone?

Therefore, x = 20
Hence the pipe M will fill the cistern in 20 hours

Given that, Relative speed of the thief and policeman = (11 – 10) km/hr = 1 km/hr
Distance covered in 6 minutes = ((1/60)*6) km = (1/10) km = 100 m.
Therefore, Distance between the thief and policeman after 6 minutes = (200 – 100) m = 100 m
