Question

Kate has the following information about her age in the current year (2022):
1. She is 30 years younger than her mother.
2. Her sister Rachel who was born in 1982, is 35 years younger than her mother.
Find Kate's age.

• A. 45 years
• B. 55 years
• C. 50 years
• D. 35 years

Answer 1

The correct option is A 45 years

Rachel's year of birth = 1982

So, her present age
= 2022 – 1982 = 40 years

Now, Rachel is 35 years younger than her mother.

So, Rachel's mother's age = 40 + 35
= 75 years

We know that Kate is 30 years younger than her mother.
So, Kate's age = 75 – 30 = 45 years.
