Question

If the monkey climb a 31 m poll. he climb 3 m in 1 minute and in next minute he slip 1 m. then how much time he need to reach bat top

Answer 1

Answer:

29 minutes

We need to consider following before solving

1. In 1 minute he climbs +3 m
2. In next 1 Minute he decends 1m i.e. climbs -1 m

Therefore, In 2 minutes he climbes

(+3)+ (-1) =2 m

Therefore in 28 Minutes he will climb upto

28 m

and in next minute he will reach top so we will not consider further any kind of decend of monkey

Therefore ,he will take total

28+1 =29 minutes
