Question
At present Neeta is thrice Sita’s age. Eight years
hence the respective ratio between Neeta and Sita’s age will be 5:2. What is Neeta’s age after 5 years?Solution
Let Sita’s present age be x years. So, Neeta’s present age = 3x years Eight years hence, Sita’s age = x + 8 years
Neeta’s age = 3x + 8 years According to the question, {3x + 8}/{x + 8} = {5/2} Or, (2(3x + 8) = 5(x + 8)) Or, (6x + 16 = 5x + 40) Or, (x = 24) So, Sita’s present age = 24 years Neeta’s present age = (3 x 24 = 72) years Therefore, Neeta’s age after 5 years = (72 + 5 = 77) years
