Question

Answer 1

Answer:

age of ram=20years

age of shyam=28years

Step-by-step explanation:

let age of ram=5x

let age of shyam=7x

age of ram after 4 years=5x+4

age of shyam after 4 years=7x+4

5x+4/7×+4=3/4

4(5x+4)=3(7x+4)

20x+16=21x+12

16-12=21x-20x

4=x

age of ram=5x

=5×4=20 years

age of shyam=7x

=7×4=28 years
