Question

Anita's mother is five younger to her father. Presently her father is 4 times old as she is. 5 years earlier her father was 7 times as old as she was born. . What was the age of her mother ?

Answer 1

Answer:Let the daughter's age be x years. Then,

Mother's age =3x years and  

Father's age=(3x+5) years

When daughter's age is 10 years,

Father's age =(3×10+5)=35 years.

When daughter was born,

Father's age=(35−10)=25 years

Step-by-step explanation:

Answer 2

Answer:

Let the age of son be x.

Thus, age of father is 4x.

After 5 years, their ages will be x+5 and 4x+5 years respectively.

As per the question, we have

4x+5=3(x+5)

⇒4x+5=3x+15

⇒x=10

Age of father will be 4x=4×10=40 years.

Thus when son is 10 years old, father is 40 years.

hope it helps you ☺☺
