Question

varun takes a certain number of roti during lunch but always wastes half a roti rosa takes half the number of roti as varun and always finishes her share after 20 days if the number of rotis that were consumed during lunch by them together is 110 (excluding the roti wasted) then find the number of roti per meal that varun and rosa take how many rotis were wasted in 20 days 

Answer 1

Every day Varun waste's 1/2 roti ,
So in 20 days he will waste 20 * 1/2 = 10 rotis .
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 .
So x + 2x = 120
⇒ 3x = 120
⇒ x = 120/3
⇒ x = 40
So Varun eat's 80 rotis (2x) and Rosa eat's 40 rotis (x).
Therefore, Varun eat's 80/20 = 4 rotis per day and Rosa eat 40/20 = 2 rotis per day.
