The question for the day is from the topic of Races.

| (1) |
200 seconds |
| |
(2) |
140 seconds |
| (3) |
220 seconds |
| |
(4) |
190 seconds |
Correct Answer - (4)
Solution:
A can give B a start of 50 metres or 10 seconds in a 1000 m race.
That is, B takes 10 seconds to run 50 metres.
Therefore, B will take (10/50) * 1000 = 200 seconds to run 1000 metres.
A who can give B a start of 10 seconds will take 10 seconds lesser to run the 1000m.
Hence, the time taken by A = 190 seconds.
