Question
When 11 years is subtracted from the present age of A
and the obtained result is divided by 3, then the present age of his nephew is obtained. If the present age of his nephew is 6 years less than the present age of A’s son who is 16 years old, then find the present age of A.Solution
Let the Present age of A be ‘x’ years Present age of his nephew = 16 – 6 = 10 years Therefore, {(x – 11)/3} = 10 Or, x – 11 = 30 Or, x = 41 Therefore, present age of A = 41 years
