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.
