Answer:
Answer is 30
Step-by-step explanation:
Let the common number be x.
Therefore, Priya age = 6x & Sona age =5x
After 15 years their ratio will be 9:8
Therefore, 6x + 15 ÷ 5x + 15 = 9 ÷ 8
By, doing cross multiplication,
8(6x + 15) = 9(5x + 15)
48x + 120 = 45x + 135
48x = 45x + 15
15 = 48x - 45x
15 = 3x
x = 15 / 3
x = 5
Therfore, Present age of Priya = 6x
= 6 x 5
= 30
Hope it helps u, my dear☺!
