Question

Raju is 10 years older than Ramu. Next year Raju's age would be double than of Ramu.What are their ages now?
​

Answer 1

Answer:

Step-by-step explanation:

Let Raju's age be x and Ramu's age be y,then,

Case 1:

x=10+y

x-y=10......(1)

Case 2:

x+1=2(y+1)

from eqn 1 and 2,

x-2y=2-1

x-2y=1......(2)

subract eqn 1 and 2,

x-y-x+2y=10-1

y=9 years

from eqn 1,

x=10+9

x=19 years

So, Raju and Ramu are 9 and 19 years old respectively

hope it helps u.....
