- Question
- Two trains of length 50 m and 65 m are moving in the same direction at 18 m/s and 17 m/s, respectively. Find the time taken by the faster train to cross the slower train.?
Options- A. 100 s
- B. 114 s
- C. 95 s
- D. 115 s
- Correct Answer
- 115 s
ExplanationAccording to the formula.
Required time = (x + y)/(u - v)
Here , x = 50 m , y = 65 m , u = 18 m/s and v = 17 m/s
? Required time = (50 + 65)/(18 - 17) = 115/ 1 = 115 s - 1. What value should come in place of the question mark(?) in the following question? (?) - 19657 - 33994 = 9999

Correct Answer: 63650
Explanation:
19657 Let x - 53651 = 9999 33994 Then, x = 9999 + 53651 = 63650 ----- 53651 -----
Correct Answer: 27474
Explanation:
x + 3699 + 1985 - 2047 = 31111
⟹ x + 3699 + 1985 = 31111 + 2047
⟹ x + 5684 = 33158
⟹ x = 33158 - 5684 = 27474.
Correct Answer: 25
Explanation:
Let 250 / √x = 10.
Then √x= 250 / 10 = 25
∴ x = 625
Correct Answer: 2938
Explanation:
Let x + 6207 - 9038 = 107
Then x = (107 +9038) - (6207)
= 2938
Correct Answer: 6513
Explanation:
Let x - 4799 = 1714
Then, x = 4799 + 1714
= 6513.
Correct Answer: 5804
Explanation:
Let 9501 - x = 3697
Then x = 9501 - 3697
= 5804
Correct Answer: 72744
Explanation:
66066 + 6606 + 66 + 6 = 72744
Correct Answer: 865
Explanation:
Let y x 48 = 173 x 240
Then y = (173 x 240) / 48
=173 x 5
= 865 .
Correct Answer: 50505
