Question

Jaya and Vinay's combined age is 72 in
the ratio 4:5. How old is Vinay?​

Answer 1

Answer:

Vinay's age will be 40 yrs

Step-by-step explanation:

let's consider :

jaya's age = 4x

Vinay's age = 5x

4x + 5x = 72

9x = 72

x = 72/9

x = 8

vinay's age = 5x

= 5 × 8

= 40.

Answer 2

Answer:

Let their ages be 4x and 5x respectively. Thus, age of Vinay = 5x = 5*8 = 40 years old.
