Question

the ages of Rahul and Lakshmi are in the ratio 5:7 four years later the sum of their ages will be 56 years what are their present ages?

​

Answer 1

Answer:

20 and 28

Step-by-step explanation:

Let their ages be 5x and 7x

Their ages after 4 years= 5x + 4 and 7x + 4

So,

5x + 4 + 7x + 4 = 56

12x + 8 = 56

12x = 48

x= 48/12

x=4

So their present ages are

5x= 5 x 4

= 20

and 7x= 7 x 4

= 28
