Answer 1

Answer:

let, mother age =x

sonnage =y

condition one

x=2+4y

if x=30

then

x=2+4y

30=2+4y

30-2=4y

28=4y

28\4=y

7=y

i.e age of son is 7 year

Answer 2

$\sf\red{Solution}$

Let the present age of the son be x years.

Age of the mother = (x + 25) years

After 8 years,

Age of son = (x + 8) years

Age of mother = (x + 25+ 8) years

= (x + 33) years

From the given information,

$\frac{x + 8}{x + 33} = \frac{4}{9}$

⇒ 9 (x + 8) = 4 (x + 33)

⇒ 9x + 72 = 4x + 132

⇒ 9x - 4x = 132 - 72

⇒ 5x = 60

⇒ x = 12

Hence, the present age of the son is 12 years.
