Question

When the son will be as old as his father today, the sum of their ages then will be 126. When
the father was as old as his son is today, the sum of their ages then was 38. Find their present
ages.​

Answer 1

Step-by-step explanation:

Let son's age be = x

Let father's age be = y

According to Case I

If x = y

Then x + y = 126

y + y = 126

2y = 126

y = 126 ÷ 2

y = 68

So father's age will be 68 years

According to Case II

If y = x

Then x+y = 38

x+x = 38

2x = 38

x = 19

So son's age will be 19 years.
