Question

Varun takes a certain number of rotis during lunch, but always wastes half a roti.Rosa takes half the number of rotis as varun,and always finishes her share after 20 days,if the number of rotis that were consumed during lunch by then together is 120 ( excluding the rotis wasted ), then find the number of rotis per meal that varun and Rosa take​

Answer 1

Answer:

As they have consumed 110 rotis in 20 days , they have taken 110 + 10 = 120 rotis. (10 are wasted). Let Rosa eat x rotis and Varun eat 2x rotis . ... Therefore, Varun eat's 80/20 = 4 rotis per day and Rosa eat 40/20 = 2 rotis per day.
