Question

Six years from now, Kirti's age will be twice the age of her brother Kunal, but 4 years ago she was four times as old as Kunal was then. Find the present age of Kunal ?​

Answer 1

Step-by-step explanation:

let kunal's age be x

2x + 6 = 4x - 4

=> 2x - 4x = -4 - 6

=> -2x = -10

=> x = -10/-2

=> x = 5

hence the present age of Kunal is 5
