Question

Two years ago, Aryan’s age was seven times the age of Kartik. Eight years hence, the age of Aryan will become twice of the age of Kartik. Find the present age of Aryan

Answer 1

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

Answer 2

Answer:

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
