Answer 1

Answer:

the correct answer is 40 years..

Step-by-step explanation:

solution:

P = 2/5 M

after 8 years

Answer 2

Step-by-step explanation:

Let their age after eight years be x and 2x respectively.

At present,

age of child = x-8

age of mother = 2x-8

ATQ,

x-8 = 2/5(2x-8)

5(x-8) = (4x-16)

5x-40 = 4x-16

5x-4x = 40-16

x = 24

2x = 48

At present age of mother = 48-8 = 40 years
