Ans 53 mins.
monkey covers metres in 2mins
now nearest even multiple of 3 near 80 is 78
so 3m in -------------> 2mins
3*26 --------------> 52 mins
78 m ---------------> 52 mins
now when it makes next jump of 5m it reaches the top in 1 extra min that is 53 mins

ans:51 min
a monkey climbs 5 meters in one min & slips 2m in other min.
therefore the monkey reach 3meters in 2min
Hence for 75 mts it takes 50 minutes
for next 5mts it takes one minute more
so total 51 minutes
