This might sound stupid, but how do we know that we need to round up 64 to 65 without losing to much time. I did this question before and it took over 2 min before i knew that i had to round 64 to 65 in order to solve the problem. Do you have any trick in mind?

last year= 320
this year = 385

((385-320)/320)*100 = (65/320 )*100 approx.. 20

(A) 2%
(B) 17%
(C) 20%
(D) 65%
(E) 83%

Percentage increase = $$\frac{(Final - Original)}{Original}*100$$

Substituting the values here

$$\frac{(385 - 320)}{320}$$* 100 = (65/320)*100 = 20% approx

First thing is you can approximate since the percentages are wide apart.

385 - 320 = 65

original amount = 320 so every 32 is 10%

20% is equal to 64 M

so answer is slightly above 20% hence C is the closest answer.
