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 them together is 120 (excluding the rotis wasted), then find the number of
rotis per meal that Varun and Rosa take. How many rotis were wasted in 20 days?
The mumber of rotis wasted, would have fed Rosa lunch for 12 days?​

Answer 1

Answer:

Answer. As there are 20 days , and every day varun waste half a roti , so he will waste 20 *(1/2) = 10 rotis . As they have consumed 120 rotis in 20 days , so they have taken 120 + 10 = 130 rotis. ... So varun eat 86 rotis and roja eat 43 rotis .Oct 12, 2017
