Question

Mira's present age is thrice of Shilpa. If Shilpa's age three year ago was x year . Then Mira's present age (in term of x),is;________years.

Answer 1

3x + 9.
Let Shilpa’s present age = y
Therefore, Mira’s present age = 3y
3 years ago : Shilpa’s age = y - 3 which according to the question equals X
Hence, if y - 3 = X, then y = X + 3
And therefore Miras present age = 3y which equals 3(X+3) = 3x+9.

Answer 2

Let Shilpa's age be x+3 (as her age three years ago was x)
Mira's present age is thrice of Shilpa's age which is equal to 3(x+3)= 3x+9
Mira's present age in terms of x is 3x+9 years
