Question

2 cows 2 days gives 2 litre milk ,how much milk gives 10 cows in 10 days

Answer 1

2 cows    2 litre  2 day
10 cows  x litre  10 days

2 * 2 * x = 10 * 2 * 10
4x = 200 
x = 50

Answer 2

10 cows give 50 litres of milk in 10 days.

Solution:

From the Given,

2 cows in 2 days gives = 2 litres of milk

Therefore, 1 cow in 2 day gives = 1 litre of milk

Therefore, 1 cow in 1 day gives = $\frac{1}{2}$ litre milk

Thus, 1 cow in 10 day gives = $\left(\frac{1}{2}\right) \times 10$ litre milk  

= 5 litres milk

Hence, the amount of milk given by 10 cows in 10 days gives =$5 \times 10$

=50 litres of milk.
