Question

Sumit is 3 times as old his son. Five year later he shall we two and a half times as old as his son. How old is sumit at present?​

Answer 1

Answer:

45 years

Step-by-step explanation:

Let Son’s present age be x years.

Then, Sumit’s present age = 3x years.

∴ 5 Years later,

3x + 5 = 5/2 × (x + 5)

6x + 10 = 5x + 25

⇒ x = 15

∴ Sumit’s present age = 45 years.

Thankyouu..

Answer 2

Answer:

let age of sumit's son be x yrs

age of his father is 3x

(x+5)*2 1/2 =3x+5

x=?

5/2x+25/2=3x+5

$\frac{25+5x}{2}$=3x+5

25+5x=6x+10

15=x

3x=45

so age of sumit is 45
