Answer 1

Answer:

Let present age of ritu is x

according to question

→Ritu's present age is one-fourth of her mother's present age

→x  = 4x

→Ritu's age eight years from now will be half of her mother's age

→2(x+8) = (4x+8)

2x+16 = 4x + 8

2x = 8

x=4

Ritu present age = 4 years

Ritu's mother age = 16 years

Answer 2

Answer:

Step-by-step explanation:

Let Mother's present age be a

So, Ritu's present age = a/4

After 8 years

Mother's age = a + 8

Ritu's age = a/4 + 8

As per the relation given

Ritu's age = 1/2 Mother's age

a/4 + 8 = 1/2 (a + 8)

a/4 + 8 = a/2 + 8/2

a/4 + 8 = a/2 + 4

8 - 4 = a/2 - a/4

4 = 2a/4 - a/4

4 = a/4

16 = a

Mother's present age = 16 years

Ritu's present age = 4 years
