Download Solution PDFGiven:
Father's age = Son's age + 30
Father's age + 10 = 3 × (Son's age + 10)
Formula used:
Let son's present age be 'x' and father's present age be 'y'.
Calculation:
y = x + 30 ...(1)
y + 10 = 3(x + 10) ...(2)
Substitute (1) in (2):
x + 30 + 10 = 3x + 30
x + 40 = 3x + 30
40 - 30 = 3x - x
10 = 2x
x = 10 / 2
x = 5
∴ The son's present age is 5 years.
