Answer:
Age of Raju = 12
Age of Ravi = 16
Step-by-step explanation:
Let the Ages of Raju and Ravi be 3x and 4x years
According to question, =
⇒ 5(3x+4)=4(4x+4)
⇒ 15x+20 = 16x+16
⇒ 15x−16x=16 - 20
⇒ −x = −4
⇒ x = 4
Age of Raju = 3 × 4 = 12
Age of Ravi = 4 × 4 = 16

Cool question (Although it is tough somewhat)
1st step is to visualize the change from C to C'
we have C'(8,-3) and C(3,-8) supposedly for C because it doesn't show any real values.. Nonetheless
from C to C' there has been a rotation of 90 degrees clockwise
proof:
Clockwise 90 degrees rotation law : (x,y) --> (y,-x) and it proves the change from C to C'
Therefor
all left to do is estimate the B point coordinates and implement the law of rotation
B(8,-7) Now implement a rotation of 90 degrees clockwise
we would get
B'(7,-8)
Hope that helps
