The chord of a circle of radius R touches at a point on the circumference of a concentric circle of radius r. the length of the chord is 24 units.
Question: What are the values of r and R?
Statement-I: r is an integer.
Statement-II: R is an integer.

Correct option is C

(R - r)(R + r) = 144
Statement - I: r is an integer.
Statement - II : R is an integer.
(R - r)(R + r) = 144 = 72 × 2 = 36 × 4
Using this we can find the values of R and r,
Since we are using both statements to answer the question.
