Answer 1

Each son should get 175 liters of milk.

Step-by-step explanation:

So the number of liters of milk given by each cow will be as follows:

1, 2, 3, .... 49

Each son should get 7 cows and all sons should get equal liters of water. So let us first find out total milk produced per day.

AP is 1, 2, 3, .... 49 with a = 1 and d = 1, n = 49

Sum of AP = n/2 (a + 1) = 49/2 ( 1 + 49) = 49 * 25 = 1225 liters.

Each son should get = 1225/7 = 175 liters of milk.
