Answer 1

Answer:

Let Vani’s age be x

 Let Vani’s father’s age be y

 Let Vani’s grand father’s age be z.

Sub, z = 84 in (3), we get  4x – 84 = 12  4x = 96  x = 24

 Sub, x = 24, z = 84 in (1) we get  24 + y + 84 = 159  y = 159 – 108 = 51  

∴ Vani’s age = 24 years  Her father’s age =51 years

Her grand father’s age = 84 years
