Question
The present age ratio of Kavya to Neha is 3:5. Seven years
ago, Neha was 5 years more than twice the age of Kavya. If present average age of Kavya, Neha and Anjali is 30 years, find the age of Anjali.Solution
ATQ,
Let present age of Kavya and Neha be 3x years and 5x years respectively.
According to question,
(5x – 7) = 2 × (3x – 7) + 5
5x – 7 = 6x – 14 + 5
x = 2
Kavya = 6
Neha = 10
Total = 30×3 = 90
Anjali = 90 – (6 + 10) = 74 years
