Q. 34.3( 47 Votes )

The sum of ages of Priyanka and Deepika is 34 years. Priyanka is elder to Deepika by 6 years. Then find their today's ages.

Class 9th MHB - Math Part-I 5. Linear Equations in Two Variables

Answer :

Let the ages of Priyanka and Deepika be 'x' and 'y' respectively.

Given,

Sum of ages is 34

⇒ x + y = 34

⇒ y = 34 - x eq.[1]

Also, Priyanka is elder to Deepika by 6 years

⇒ x = y + 6

Using eq.[1] we have

⇒ x = 34 - x + 6

⇒ 2x = 40

⇒ x = 20

Putting this value in eq.[1]

⇒ y = 34 - 20 = 14 years.

Hence, Age of Priyanka = x = 20 Years

Age of Deepika = y = 14 years.
