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 20days,if the number of rotis that were consumed during lunch by them together is 120(excluding the rotis wasted ,then find the number of roties per meal that varun and Rosa take .how many roties were wasted in 20 days ?

Answer 1

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.

Let rosa eats x rotis and varun eats 2x rotis .
So x +2x = 130
Hence 3x = 130
Or x = 43(approx)
So varun eat 86 rotis and roja eat 43 rotis .
So varun eat 86/20 = 4 rotis per day(approx)
And Rosa eat 43/20 = 2 rotis per day(approx)

Answer 2

The Answer is:

Varun = 4 rotis per day

Rosa = 2 rotis per day

Step-by-step easy explanation:

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 eats 80 rotis (2x) and Rosa eats 40 rotis (x).

Therefore, Varun eat's 80/20 = 4 rotis per day and Rosa eat 40/20 = 2 rotis per day.
