Question

the age of Priya and Riya are in the ratio of 3 : 5 if the sum of their ages is 56 then find their ages​

Answer 1

Step-by-step explanation:

let the age of priya be x and age of riya be y.

according to the question,

x/y=3/5. . . . . 1

and also,

x+y=56. . . . . 2

from 1 and 2

we get

5x-3y=0 and x+y=56

multiplying equation 2 by 3

we get ,

5x-3y=0 and 3x+3y=168

by using elimination method, we get 7x=168

x=24

and putting the value of x in equation 2

24+y=56

y=56-24

y=32

hence priya's age is 24 years old and priya's age is 32 years old.
