Step-by-step explanation:

to find out Venkat's age we have to first find Palaks age.

Given,

Mehak's age = 5 years

palak is younger by mehak by = 2 years

so, 5-2 = 3 years.

now,

let Venkat's present age be x.

according to question.

deduct 6 from Venkat's age = x - 6

divide the result by = 18 so, x - 6/18.

now equation is

x - 6 / 18 = 3 ( as the result is equal to Palaks age )

\frac{x - 6}{18} = 318x−6=3

→ x - 6 = 3 × 18

→ x - 6 = 54

→ x = 54 + 6 = 60

→ x = 60.

hence, Venkat's present age is 60.

verifying

deduct 6 from 60 = 54

divide 54 by 18 = 3

3 = palak's age.
