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

Answer:

(1) 100 MIN

Step-by-step explanation:

AS the monkey climbs 3m in one minute and silps down 1m in another one minute so we can say in two minutes monkey climbed 2m

if

$2metre = 2 \: minute \\ 100 \: metre \: \: = \: \: \: \: ? \\ \\ then \: by \: cross \: multiplication \\ \\ 100 \times 2 \div 2 = 100 \: minutes$
