A monkey could climb 6 m of a round pole in one minute but slipped 3 m in the next minute. What time will it take to reach the top of the pole which is 12 m long? |
A) \[14\frac{2}{3}\min \]
B) \[4\,\,\min \]
C) \[11\,\,\min \]
D) \[9\,\,\min \]
Correct Answer: D
Solution :
Since, monkey climbs 6 m in 1 min but in the next minute monkey slips 3 m. |
Therefore, in 2 min, 3 m height is climbed. |
\[\therefore \]12m distance will be covered in \[2\times 4=8\]min. |
But 1 min was wasted in slipping. |
\[\therefore \]Total time = 8 +1= 9 min |
