The age of a girl in months is equal to the age of her grandmother in years. If the difference between
their ages is 66 years, find their ages.​

Answer 1

Answer:

let age of a girl be x and the age of her grandmother y

if the age of a girl in months is equal to the age of her grandmother in years,

12x=y.....eq.1

If the difference between their ages is 66 years,

y-x=66

y=66%2Bx.....eq.2

from eq.1 and eq.2 we have

12x=66%2Bx

12x-x=66

11x=66

x=66%2F11

x=6

->The age of a girl

y=66%2Bx

y=66%2B6

y=72

->the age of her grandmother

12x=12%2A6=72

->The age of a girl in months which is equal to the age of her grandmother in years
