Net distance travelled by monkey in 2 min = 3 m
∴ In 10 minutes, distance travelled (climbed)
= 15 m
As it is given in the question that in first minute it climbs 6 metres and in other minute it slips down 3 metres. And this happens alternatively.
Hence monkey will travel remaining 6 metre in next minute
∴ Total time taken = (10 + 1) = 11 min

The monkey climbs a 21 m long pole by climbing 6 m in the first minute and slipping 3 m in the next minute. We need to find out how much time it will take for the monkey to reach the top of the pole.
Let's calculate the time taken by the monkey step by step:
1. First minute:
- The monkey climbs 6 m.
- The remaining distance is 21 m - 6 m = 15 m.
2. Second minute:
- The monkey slips 3 m.
- The remaining distance is 15 m - 3 m = 12 m.
3. Third minute:
- The monkey climbs 6 m.
- The remaining distance is 12 m - 6 m = 6 m.
4. Fourth minute:
- The monkey slips 3 m.
- The remaining distance is 6 m - 3 m = 3 m.
5. Fifth minute:
- The monkey climbs 6 m.
- The remaining distance is 3 m - 6 m = -3 m.
At this point, the monkey has climbed past the top of the pole by 3 m. Therefore, it takes 5 minutes for the monkey to reach the top of the pole.
So, the correct answer is option 'A' - 11 minutes.
Explanation:
- The monkey climbs 6 m in the first minute and slips 3 m in the next minute.
- By repeating this pattern, we can calculate how many times the monkey will climb and slip to cover the remaining distance.
- By doing this calculation step by step, we find that it takes 5 minutes for the monkey to reach the top of the pole.
Let's calculate the time taken by the monkey step by step:
1. First minute:
- The monkey climbs 6 m.
- The remaining distance is 21 m - 6 m = 15 m.
2. Second minute:
- The monkey slips 3 m.
- The remaining distance is 15 m - 3 m = 12 m.
3. Third minute:
- The monkey climbs 6 m.
- The remaining distance is 12 m - 6 m = 6 m.
4. Fourth minute:
- The monkey slips 3 m.
- The remaining distance is 6 m - 3 m = 3 m.
5. Fifth minute:
- The monkey climbs 6 m.
- The remaining distance is 3 m - 6 m = -3 m.
At this point, the monkey has climbed past the top of the pole by 3 m. Therefore, it takes 5 minutes for the monkey to reach the top of the pole.
So, the correct answer is option 'A' - 11 minutes.
Explanation:
- The monkey climbs 6 m in the first minute and slips 3 m in the next minute.
- By repeating this pattern, we can calculate how many times the monkey will climb and slip to cover the remaining distance.
- By doing this calculation step by step, we find that it takes 5 minutes for the monkey to reach the top of the pole.
