Question

varun takes a certain number of rotis during lunch, but always wasstes 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 themm together is 120 (excluding the rotis wasted), then find the nuoober of rotis per meal that varun and Rosa take. How many rotis were wasted in 20 days?

Answer 1

let the number of rotis of varun be X
let the number of rotis of Rosa be X/2
So half of varun rotis are wasted
so number of rotis ate by varun will be X/2
so varun+rosa i.e (X/2+x/2)* 20 days=120
then x=6
so varun rotis=6 so half are wasted=3 so for 20 days it will be 20*3=60
