1. A monkey climbs a 60 m high pole.s In first minute he climbs 6 m and slips down 3 m in the next minute. How much time is required by it to reach the top?
- A. 35 minutes
- B. 35 minutes
- C. 35 minutes
- D. 35 minutes
Answer: Option C
Explanation:
A monkey climbs 6 m in 1st minute and slips down 3 m in next minute
i.e. Monkey climbs 3 meters in 2 minutes.
Then he climbs in one minute = 3/2 m.
But in the last minute, he climbs 6 m as he gets on the top so there is no slip.
The time required = 2 × 54/3 + 6/6
= 37 minutes.
