Delphi TVS Aptitude Test
1. In a covering a certain distance, the speeds of A and B are in the ratio of 3:4. A takes 30 minutes more than B to reach the destination. The time taken by A to reach the destination is?
A. 1 hour
B. 1 1/2 hour
C. 2 hours
D. 2 1/2 hour
Explanation:
Given, Ratio of speeds = 3:4
Ratio of times taken = 4:3
Suppose A takes 4x hrs. and B takes 3x hrs. to reach the destination.
Then, 4x - 3x = 30/60 => x = 1/2
Time taken by A = 4x hrs. = 4 * 1/2 = 2 hrs.
2. I bought a book for Rs 60, I sold off to a friend for Rs 70 but after a while I felt sorry, that I sold it and bought it back for Rs 80, how much loss did I incur?
A. Rs 10
B. Rs 20
C. No loss, no gain
D. Rs 15
Explanation:
Given, CP of the book= Rs 60.
And, SP of the book= Rs 70
Then, Profit=Rs 10
Again, 2nd CP = Rs 80
Hence, the total loss =80-70=10.
3. A alone can do a piece of work in 6 days and B alone in 8 days. A and B undertook to do it for Rs 3200. With the help of C, they completed the work in 3 days. How much is to be paid to C?
A. Rs 375
B. Rs 400
C. Rs 600
D. Rs 800
Explanation:
C's 1 day's work = 1/3 - (1/6 + 1/8) = 1/3 - 7/24 = 1/24.
Then, A's wages: B's wages: C's wages
=> 1/6: 1/8: 1/24 = 4:3:1
Hence, C's share = 1/8 * 3200 = Rs 400.
4. A, B and C started a business with capitals of Rs 8000, Rs 10000 and Rs 12000 respectively. At the end of the year, the profit share of B is Rs 1500. The difference between the profit shares of A and C is?
A. Rs 300
B. Rs 400
C. Rs 500
D. Rs 600
E. None of these
Explanation:
Given, Ratio of investments of A, B and C is 8000: 10000: 12000 = 4: 5: 6
And also given that, profit share of B is Rs 1500
=> 5 parts out of 15 parts is Rs 1500
Now, required difference is 6 - 4 = 2 parts
Required difference = 2/5 (1500) = Rs 600
5. If Rs 510 be divided among A, B, C in such a way that A gets 2/3 of what B gets and B gets 1/4 of what C gets, then their shares are respectively:
A. Rs 120, Rs 240, Rs 150
B. Rs 60, Rs 90, Rs 360
C. Rs 150, Rs 300, Rs 60
D. None of these
Explanation:
According to the question,
(A = 2/3 B and B = 1/4 C) = A/B = 2/3 and B/C = 1/4
=> A: B = 2:3 and B:C = 1:4 = 3:12
=> A: B:C = 2:3:12
Hence,
A's share = 510 * 2/17 = Rs 60
B's share = 510 * 3/17 = Rs 90
C's share = 510 * 12/17 = Rs 360.
6. The current of a stream runs at the rate of 4 kmph. A boat goes 6 km and back to the starting point in 2 hours, then find the speed of the boat in still water?
A. 10 kmph
B. 21 kmph
C. 8 kmph
D. 12 kmph
Explanation:
Let the speed of the stream be S.
And, Speed in still water = x.
So, S = 4.
Let the speed of the boat in still water be x.
=>Speed in downstream = x + 4.
And, Speed in Up-stream = x - 4.
=> 6/ (x + 4) + 6/ (x - 4) = 2.
=> x = 8.
7. In how much time would the simple interest on a certain sum be 0.125 times the principal at 10% per annum?
A. 1 1/4 years
B. 1 3/4 years
C. 2 1/4 years
D. 2 3/4 years
Explanation:
Let sum = x. Then, S.I. = 0.125x = 1/8 x, R = 10%
Time = (100 * x) / (x * 8 * 10) = 5/4 = 1 1/4 years.
8. Find the cost of fencing around a circular field of diameter 28 m at the rate of Rs1.50 a meter?
A. Rs150
B. Rs132
C. Rs100
D. Rs125
Explanation:
Area of the field= 2 * 22/7 * 14 = 88.
Hence, the fencing cost = Rs 88 * 1.50 = Rs 132.
9. A pupil's marks were wrongly entered as 83 instead of 63. Due to the average marks for the class got increased by half. The number of pupils in the class is:
A. 10
B. 20
C. 40
D. 73
Explanation:
Let there be x pupils in the class.
Total increase in marks = (x * 1/2) = x/2
=> x/2 = (83 - 63) => x/2 = 20 => x = 40.
10. The H.C.F of two numbers is 11 and their L.C.M is 7700. If one of the numbers is 275, then the other is:
A. 279
B. 283
C. 308
D. 318
Explanation:
Other number is = (11 * 7700)/275 = 308.

19. Data Sufficiency:
Question: Among T, V, B, E and C, who is the third from the top when arranged in the descending order of their weights?
Statements:
(I) B is heavier than T and C and is less heavy than V who is not the heaviest.
(II) C is heavier than only T.
A. I alone is sufficient while II alone is not sufficient
B. II alone is sufficient while I alone is not sufficient
C. Either I or II is sufficient
D. Neither I nor II is sufficient
E. Both I and II are sufficient
Explanation:
From I, we have: B > T, B > C, V > B. Thus, V is heavier than each one of B, T and C. But V is not the heaviest. So, E is the heaviest. Thus, we have the order. E>V>B>T>C or E>V>B>C>T. Clearly, B is third from the top.

A. Only either I or IV follows
B. Only either I or II follows
C. Only either I or III follows
D. None follows
Explanation:
Since both the premises are particular, no definite conclusion follows. However, I and III involve only the extreme terms and form a complementary pair. Thus, either I or III follows.
