In 10 jumps.
Explanation-
                    If he jumps 2m high and falls 1m, 
 Then 2-1 = 1m
Therefore he will jump only 1m high.
Hence, 10*1 = 10m
  • 0
10m high

The answer would be 10 jumps as:-
The monkey would be able to jump 2m high and fall 1m on every jump. That means the expression would be
2-1= 1m on every jump.
If he repeats this process until he reaches 10m, it would take 10 jumps to come out of the well as 
1x10=10m
​The full expression can be written as 
(2-1)x10= 10m
​Hence the monkey would come out of the well after 10 jumps.
