Question: What is the value of c in the circle shown above?

We can conclude that all the triangles we see are right angle similar triangles here so we already have relations among a, b and c

Statement 1: a = 2b

No exact dimension of any side of triangle or the radius of circle hence

NOT SUFFICIENT

STatement 2: b^2 = ac
No exact dimension of any side of triangle or the radius of circle hence

NOT SUFFICIENT

COmbining the two statements

No exact dimension of any side of triangle or the radius of circle hence

NOT SUFFICIENT


ANswer: Option E

S1 - a = 2b
No value given. insufficient.
S2 - b^2 = ac
No value given. insufficient.

Combining also insufficient.
Answer E.
