Answer»

Answer:

let the present AGE of Aryan be= x and Kartik be =y

Step-by-step explanation:

(x-2)= 7(y-2)=x-7

y+12= 0..........eq1

acc to second CASE..

(x+8)=2(y+8)

x-2-8 =0 .........eq2

solve EQ 1 and second

x-7y=-12

x-2y=8

5y=20

y=4

PUT y in eq2

x-10=8

x=18 hence Aryan present age is 18
