Question

Harsha's present age is 40 years and Ritu's present age is 60 years. How many years ago was the ratio of their ages 3:5? (A) 10 years (B) 20 years (D) 5 years (C) 37 years​

Answer 1

Answer:

10 years is the correct answer. (A)

Step-by-step explanation:

In Context to the given question; Current ages of Harsha's and Ritu's age is given

we have to find how many years ago was the ratio of their ages 3:5

Given ;

Current age of Harsha's = 40 years

Current age of Ritu's = 60 years

To check the ratio of their ages years ago ;

we have subtract the ages from the option and select he appropriate one

1). 10 years ago;

Age of Harsha's = 40 - 10 = 30

Age of Ritu's = 60-10 = 50

Ratio of their ages = 30:50 = 3:5

2). 20 years ago;

Age of Harsha's = 40 - 20 =20

Age of Ritu's = 60 - 20 = 40

Ratio of their ages = 20:40 = 2:4

3). 5 years ago

Age of Harsha's =40 - 5 =35

Age of Ritu's = 60 -5 =55

Ratio of their ages = 35: 55 = 7:11

4). 37 years ago

Age of Harsha's = 40 - 37 = 3

Age of Ritu's = 60 - 37= 23

Ratio of their ages = 3:23

Therefore;

10 years is the correct answer.
