A monkey climbs 6 mts and fals 3mts in alternate mins.then time taken to climb a tree of 60 mts
Read Solution (Total 3)
-
- In 1st min , monkey climbs up 6mts
Int 2nd min, if falls 3mts --> so 6-3= 3mts
So In 2 mins, It can climb 3mts
In 10 mins, 10/2 * 3 = 15 mts
In 20 mins, 20/2 * 3 = 30 mts
In 30 mins, 30/2 * 3 = 45 mts
In 34 mins, 34/2 * 3 = 51 mts
At 35th min, It ll climb up 6 mts ... So 51+6=57 mts
At 36th min, it ll fall 3 mts ... So 57-3 = 54 mts
At 37th min, It ll climb up 6mts... So 54+6 = 60 mts...
The tree is of height 60 mts... So once it reach the top, it ll not fall back...
[Note here the monkey ll climb up 6mts in every odd mins nd falls 3mts in every even mins... Bcozzz it starts by climbing up..]
