Question
When 19 years is subtracted from the present age of A
and the obtained result is divided by 5, then the present age of his nephew is obtained. If the present age of his nephew is 10 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 – 10 = 6 years Therefore, {(x – 19)/5} = 6 Or, x – 19 = 30 Or, x = 49 Therefore, present age of A = 49 years
