My grandfather was 8 times older than me 16 years ago. He would be 3 times of my age, 8 years from now. Eight years ago, what was the ratio of my age to that of my grandfather?

YOUR ANS IS:—

Let the present age of your be x years

And, Let the present age of your grandfather be y years

Sixteen years years ago:―

Your age sixteen years ago was = (x ― 16)

And, Your grandfather age sixteen years ago

= (y ― 16)

A/Q

=> (x – 16) = 8 (y –16)

=> x – 16 = 8y – 128

=> x – 8y = –112 --------------------(i)

Eight years from now:―

Your age eight years from now = (x + 8)

And, Your grandfather age eight years from now = (y + 8)

A/Q

=> (x + 8) = 3 (y + 8)

=> x + 8 = 3y + 24

=> x – 3y = 16 -----------------------(ii)

(i) – (ii)

=> x – 8y – x + 3y = –112 –16

=> –5y = –128

=> y = 128/5 (it is not possible)
