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
