Correct Question :- Nisha was twice as old as old as ruchi 8 years ago however 10 years from now she will be 3/2 times of Ruchi .what is nisha present age .
Answer :-
Let nisha present age is x years and ruchi present age is y years .
so,
8 years ago :-
→ Nisha = 2 * Ruchi
→ (x - 8) = 2(y - 8)
→ x - 2y = (-8) ------------ Eqn.(1)
also,
10 years from now :-
→ Nisha = (3/2) Ruchi .
→ (x + 10) = (3/2)(y + 10)
→ 2x + 20 = 3y + 30
→ 2x - 3y = 10 --------- Eqn.(2)
Multiply Eqn.(1) by 3 and Eqn.(2) by 2 and subtracting the result from Eqn.(1) ,
→ 2(2x - 3y) - 3(x - 2y) = 2*10 - 3(-8)
→ 4x - 3x - 6y + 6y = 20 + 24
→ x = 44 years (Ans.)
Hence, Nisha Present age is 44 years.
