Answer / anonymous
ans-40 hours
The question clearly says in 1 hr it climbs 3mtr but in next hour(alternate hour) it slips 2 mtr so in total of 2 hours its action is
2hr=3mtr(climb)-2mtr(slip back)=1mtr
so it takes 2hr to climb 1 mtr
that straight away makes 40 hours to climb 20 mtrs.

Answer / kambali
alternate hour is the heavy word here. it means that it takes 1 hr to get up 3 mtrs and then 1 hr to get down 2 mtrs. So that means it takes 2 hours to move 1 mtr. Thus to move 17 mtrs it takes 34 hours, the next 1 hour to move 3 mtrs up which makes the 20 mtrs and the destination.
Thus 35 hours is the correct one and not 18(Alternate hours is important).

Answer / khalon
2 hours = 6mts - 2 mts = 4mts
20 / 4 = 5
5 x 2 hours = 10 hours
answer = 10 hours
10 hours x 3mts = 30 mts
5 x -2mts = -10mts (alternate monkey hours falling)
30 - 10 = 20 mts for 10 hours climb
