Answer 1

Hey,sup!

As per the question,

30 cows eat 5 kg grass in 20 days
so 30 cows eat grass in 1 day = 5/20 = 1/4 kg.

So 15 cows will eat grass in 1 day= 1/4/2= 1/8kg.
So 15 cows wil eat grass in 25 days= 1/8 ×25.
=3.125kg

Hope it helps.

Answer 2

Number of cows = 30

30 cows eat how much grass= 5kg

30 cows eat 5kg grass in how many days= 20 days

So 30 cows eat grass in one day= 5/20= 0.25 gems that mean 1/4kg

So we should calculate this for 15 cows.

15 cows will eat grass in one day= 1/4/2=2/8kg

So 15 cows will eat grass in 25 days= 1/8× 25= 3.125kg.

So 3.125kg of grass will 15 cows eat in 25 days.
