Question

A man has 25 cows. All cows are numbered 1 to 25. All cows provide as many liters of milk as their number. That is, cows of number 5 give 5 liters and cows of number 8 provide 8 liters of milk.
The man has 5 sons. Each son has to give five cows. However, each son should get the same amount of milk.
So, what number of five cows should be given to each son?

Answer 1

By using the given pattern each cow will give 65 litres of milk and each son will get 5 cows.

Explanation:

• Now according to the statement of the question.
• Draw a square and then make 5 sets each set having 5 number of horizontal or vertical rows of cows.

If we follow this pattern

17   24   1    8    15

23   5   7    14    16

4     6   13   20  22

10   12   19   21   3

11    18   25   2   9

The sum of each horizontal or vertical row will be 65.

Each cow will give 65 litres of milk and each son will get 5 cows.
