Answer 1

Answer:

the ratio of the age of rahul and laxmi=5:7

let the ages of rahul and laxmi =5×+4,7×+4

four years later the sum of their ages

four years later the sum of their ages =56 years

5×+4=7×+4=56

12×+8=56

12×=56-8

12×=48

×=48/12

×=4

the present age of rahul=5×=5×4=20years

the present age of laxmi=7×=7×4=28years
