Question

Age of Amit and Ram is in the ratio of 5and7. Four years later
now the ratio
of
their
ages will be 3:4. Find there present
age.​

Answer 1

Let the ages of Amit and Ram are 5x and 7x

Now after four years

5x+4/7x+4=3/4

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

20x+16=21x+12

20x-21x=12-16

-x=-4

x=4

Now their present ages are 5*4=20 and 7*4=28
