Correct Answer: 10 years


Solution : Given:

Joan's present age = 42 years

and, Kelvin's present age = 26 years

Before years let the age was X years.

According to the question →

Kelvin's age = 1 / 2 Joan's age

⇒ 26 - X = 1 / 2 ( 42 - X )

⇒ 52 - 2X = 42 - X

⇒ X = 52 - 42 = 10 years.

So, 10 years ago Kelvin's age was half of Joan's age.

Hence, third option is correct.
