63, 84, 96 are short/surplus on 85 by {-22, -1, +11} respectively

i.e. current short in maintaining average = -22-1+11 = -12

So the score required in next two tests = 85*2 + 12 = 182

i.e. Average in next two tests = 182/2 = 91

$$63 + 84 + 96 + n + n = 85*5$$

Or, $$2n + 243 = 425$$

Or, $$2n = 182$$

Or, $$n =91$$, Answer must be (B)

sum of three scores= 243
243 + 2x = 85 * 5
x = 91
IMO B
