Question 1
1 / -0

Prateek is 48 years old. Shubham, his son, asks his father about his age, to which the father replies that after four years, he will be six years older than twice his age at that time. Find the present age of Shubham.

A
23 years

B
22 years

C
20 years

D
19 years

Solution

Prateek's present age = 48 years
Suppose, Shubham's present age is 'x' years.

Prateek's age after four years = 52 years
Shubham's age after four years = (x + 4) years

According to the question,
2(x + 4) + 6 = 52

2x + 8 + 6 = 52
2x = 52 - 14

2x = 38
x = 19
