Mother is 30 years older than Anita. The ratio of

Anita’s age to her mother’s age , 10 years ago was 1

:7. Find Anita’s present age.​

Answer 1

Answer:

let anita age be x

mother= x+30

10 years ago

x:x+30 = 1:7

so ten year before x-10/x+30-10=1/7

x-10/x+20=1/7

by cross multiplication

7x-70=x+20

6x=90

x=15 years

anitas age is 15 years
