A monkey at the bottom of a well which is ten feet deep tries to climb out. Each hour he jumps up three feet and slips back two. At that rate, how long will it take the monkey to reach the top?
A6 hours
B7 hours
C8 hours
DNone of these
Ans 3:
Class : Class 7
But why it should be (C)? See, Well's depth = 10 FeetMonkey Jumps each hour = 3 FeetMonkey Slips back after a jump = 2 FeetMeans, the monkey jumps each hour 1 foot since 3-2=1 Foot1 hour = 1 footSo, 10 hours = 10 feet. So, the correct option is (d).

Jumping 3 feet and slipping 2 feet implies that each hour the monkey climbs 1 foot and so that way for 7 feet he will climb for 7 hrs. then in 8th hour, he will jump 3 feet and since he'll b at the top, so he 'll jump out of that well without slipping another 2 feet. That makes it 8 hrs in total.
