Reading the question carefully...
Monkey climbs 6m/min...it slips by 2m evey alternate min
which means it climbs 6m and slips by 2m...
So,
1st min->6m
2nd min->((6+6)-2)=10
So,for 5*(2 min) i.e for 10 min it would have climbed 50
m...(Considering it slips by 2 m in 10th min)
Here, in the 10 min if it climbs 6 m and doesnot slip, the
answer is 10 min. If it slips, then for 2 m i.e 50m to 52
m, it would be (2/6)*60=20 seconds.
So, answer would be 10 min,20 seconds.
