Answer:

This is verified Answer

Step-by-step explanation:

Present Age of Ravish =y

Present Age of Aarushi =x

According to Question 

7 Years ago,

y−7=7(x−7)⇒7x−y−42=0.............(1)

and 3 Years from now

y+3=3(x+3)⇒3x−y+6=0............(2)

From (1) and (2)

(1)−(2)⇒7x−3x−y+y−42−6=0⇒4x=48⇒x=12

putting x=12 in Equation (2)

we get,

3×12−y+6=0⇒y=42

ANSWER :Y =42
