Answer 2

Grandfather’s age = Granddaughter’s age + 54 years
10x = x + 54
Transposing x to L.H.S, we obtain
10x − x = 54
9x = 54
x = 6
Granddaughter’s age = x years = 6 years
Grandfather’s age = 10x years = (10 × 6) years = 60 years

Answer 3

g = 10d
10d = d+54
9d = 54
d = 6

g = 10d
g = 10(6)
g = 60

where d is daughter and g is grandfather
