Question

the sum of tha present ages of avinash and ravi is 80 years. Two time of avinash age is 10 years more than ravi's age. find their present ages.

Answer 1

let Ravi's age be x-10
let avinash's age 2x

$2x + x - 10 = 80$
$3x - 10 = 80$

$3x = 80 + 10 = 90 \\ \\ x = 90 \div 3 = 30$
therefore, avinash's age = 2x = 30× 2= 60
therefore, Ravi's age = x-10 = 30-10 = 20
