The explanation provided on the test is not very informative. It says "Solve"
Any hint?

Given
$$\frac{RA}{RB}$$=$$\frac{7}{9}$$⇒RB>RA

This works only if the centre A is tangent to the centre O, then
OA=RO−RA

Similarly If the circle with center B is tangent to the circle with center in O we would have:

OB=RO−RB

Therefore we would have RB>RA and OA>OB.

I think some point is missing in the ques.
