Question

A monkey is climbing a rope of length 100 m. He climbs 3m in one minute and slips down by
1 m in another one minute because of rope being slippery(it takes him completely one minute
time to slip down one meter). Now again he climbs 3m in one minute and in another one
minute slips down one meter. This climbing and slipping continues till he reaches the top of
rope. How much times he takes to reach the top of the rope?
1) 100 min 2) 98 min 40 sec
3) 98 min 38 sec 4) none of above​

Answer 1

98 minutes 38 seconds to come the rope

Answer 2

Answer:

As we know,ignoring all the other points we can say that the monkey will take

3m in 1 minute so

100 m in 33 minutes..

So now we will start by using the number line to solve the Question:

(minute in short i will write (min) don't be confused.)

1min= 3m

2min=3-1m

3min=2+3m

4min=5-1=4m

5min=4+3=7m

6min=7-1=6m

7min=6+3=9m

8 min= 9-1=8m

9 min= 8+3=11m

10min=11-1=10m

and so on.....

So in short we can say:

In every 10 min he covers 10 m

so 100min he will cover 100m..

HOPE ITS CORRECT PLEASE TELL ME IF IT IS...
