Answer 1

Answer-

Let, the present age of Mahesh son's be 'x '

Then the age of Mahesh = 4x

After 10 years their ages will be,

=>4x + 10 = 2(x +10)

=>4x +10= 2x+20

=>4x-2x=20-10

=>2x=10

=>x= 10/2

=>x= 5

Therefore the present of Mahesh' s is 5 years

Answer 2

$\huge\underline{\bf \orange{AnSweR :}}$

Let the number be 'x'

→ 4x + 10 = 2(x + 10)

→ 4x + 10 = 2x + 20

→ 4x - 2x = 20 - 10

→ 2x = 10

→ x = 10/2

→ x = 5 Ans.
