3. Assume that Alia Bhatt is younger than Priyanka Chopra by 5 years. Now, if their ages are in the ratio of 4:5, how old is Alia Bhatt
O
b) 15 years
a) 20 years
C) 25 years
O d) 39 years
​

Answer 1

Answer:

(a) 20 years

Step-by-step explanation:

let Priyanka's age be X

then Alia's age = X - 5

ratio of their age = 4:5

i.e. 4/5 = X-5/X

on cross multiplication

4X = 5(X-5)

4X = 5X - 25

25 = 5X - 4X

25 = X

so Priyanka's age = X = 25

therefore Alia's age = X-5 = 25 - 5 = 20 years
