Question

The present ages of anu and priya are in the ratio of 9:10. Find the present age of priya if anu is 2 years younger to priya?

Answer 1

Answer:

Priya's present age is 18

Anu's present age is 16

Step-by-step explanation:

let their present age be x and y

according to question:

10y=9x-2 ......eq(1)

y=x-2 ......eq(2)

putting eq(1)&(2),we get

10y-9x=-2

y-x=-2

(multiply eq(1) by 10)

10y-9x=-2

10y-10x=-20

- + +

x=18

from eq(1):

y=x-2

y=18-2

y=16
