Four friends were born in consecutive years. the sum of their ages is 62. what is the age of the oldest friend?

Answer

Find out the what is the age of the oldest friend .

To prove

As given

four friends were born in consecutive years.

Let us assume first friend age = x

Second friend age = x + 1

Third friend age = x + 2

Fourth friend age = x + 3

The sum of their ages is 62.

Than the equation becomes

x + x + 1 + x + 2 + x + 3 = 62

4x + 6 = 62

4x = 62 - 6

4x = 56

x = 14 years.

The oldest friend age = x + 3

                                   = 14 + 3

                                  = 17 years.

Therefore the  age of the oldest friend is 17 years.
