Question
Find the maximum number of people who liked all three actors.
Answer: Option A
:
A
As we know, S = I + 2 II + 3 III
and X = I + II + III
S - X = II + 2 III
If we want to maximize exactly III. We need to put exactly II = 0
(S−X)2⇒(224−120)2=52
Short Cut: - Maximum of all can be directly calculated as
S−Xn−1, Where n is number of things.
Answer is (224−120)2=52. Option (a)
