Question

Sneha's age is [{(3/2^2}^4] years. Her sister Neha's age is (5/2)^2 times of Sneha's age. The age of of Sneha's father is 8 times the age of Neha. Now answer the following in simplified form and find the age of Sneha, Her father and sister.​

Answer 1

Answer:

Let present age of Sahil =x years

Let present age of Sahil's mother =y years

The present age of Sahil's mother is three times the present age of Sahil.

So,

y=3x (1)

After 5 years their ages add to 66 years.

After 5 years Sahil age =x+5

After 5 years Sahil mother age =y+5

Now,

x+5+y+5=66

x+y+10=66

x+y=66−10

x+y=56 .(2)

From (1) and (2),

x+3x=56

4x=56

x=14 years

From (1),

y=3x

=3(14)

=42 years

present age of Sahil =14 years

present age of Sahil's mother =42 years
