Question

the age of madhu is thrice the age of her daughter. ten years ago the ratio of daughter age to that of madhu was 1/7.find their present age.

Answer 1

Hey

Here is your answer,

Let present age of Madhu's daughter = x year

So, present age of Madhu = 3x years

Given, 10 years ago, the ratio of age of Madhu's daughter and Madhu is 1:7.

So, 10 years ago, Madhu's age = 3x-10 and her daughter's age = x-10

According to question,

x-10/3x-10 = 1/7
7(x -10) = 3x -10
7x - 70 = 3x - 10
7x - 3x = -10 + 70
4x = 60
X = 60/4
X = 15

Therefore, Madhu's age = 15 years and her mother's age
= 3x 15
= 45 years.

Hope it helps you!
