$\rule{100}2$

It is given that,

• Son is three times as old as her mom
• After 5 years, the sum of their ages will be 70 years.

Let the age of son be ' x '

So her mother's age will be ' 3x '

After 5 years,

Son = x + 5

Mother = 3x + 5

Now,

According to Question :

x + 5 + 3x + 5 = 70

→ 4x + 10 = 70

→ 4x = 70 - 10

→ 4x = 60

→ x = 60/4

∴ x = 15

Hence,

Son is 15 years old.

Her mother : 3 × 15 = 45 years old.

Answer 2

Answer:

Age of son = 15 years and Age of mother = 45 years

Explanation:

Let the age of son be x years.

So, age of mother = 3x years

Also, given that after 5 years the sum of their ages will be =70

Age of son after 5 years = (x+5) years

Age of mother after 5 years = (3x+5) years

Given,

=> x+5+3x+5 = 70

=> 4x+10 = 70

=>4x = 60

=> x = 15 years

So, age of mother = (3*15) years

                              = 45 years
