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:RAJU=X

RAJU'S FATHER=4X

AFTER 5 YEARS

X+5=RAJU

4X+5=RAJU'S FATHER

SO,

4X+5=3(X+5)

4X+5=3X+15

4X-3X=15-5

1X=10

X=10

 

THERFORE  

RAJU'S AGE IS 10

RAJU'S FATHER AGE IS 4

Step-by-step explanation:

Answer 2

Let the age of Ramu = x

Then the age of Raju = x+10

One year after,

Ramu's age = x+1

Raju's age = x+10+1 = x+11

According to question,

2 * Ramu's age = Raju's age

2 * (x+1) = (x+11)

2x+2 = x+11

2x-x = 11-2

x = 9

Ramu's age = 9 years

Raju's age = 9+10 = 19 years
