Question

Radha can do a work in 20 days while Meera can do the work in 25 days. If they work together, how long will it take to get the work done

Answer 1

Answer:

11 1/9 Days

Step-by-step explanation:

As it's given that,

radha can complete work in 20 days,

meera can complete the work in 25 days,

The LCM of 20 & 25 is 100, which we consider as total Work=100,

Therefore

radha’s One day work=100/20=5,

meera’s One day work=100/25=4,

So together they can complete 9 units per day,

Therefore No of days =100/9= 11 1/9 Days
