Question

A girl is 18 years younger than her mother . In 3 years time the sum of their ages will be 48. How old is the girl now???
Solution plz​

Answer 1

Answer:

Step-by-step explanation:

Let the girl's age be = x

Mother's age would be = x+18

After 3 years,

The girl's age would be = x+3

Mother's age would be = x+18+3 = x+21

According To The Question,

(x+3)+(x+21)=48

2x+24=48

2x=48-24=24

x=24/2

x=14

Therefore girl's age is 14

Let us take the age of the girl as x and age of mother as x+18.

After two years ,

Age of girl = x+3

Age of mother = x+21

(x+3)+(x+21) = 48

2x+24 = 48

2x = 24

x = 12

Present age of girl = 12 years
