Suppose you are to calculate 5.26% of 760 as a sub-step of a DI calculation say something like
(526/200) X (760/100) => {(5.26/100) X (760/1)} 1/20
You should know the equivalent fraction of 5.76% (It is actually 1/19 ), it reduces to (40) X 1/20 = 2
This can save you vital 15 – 20 seconds (at least) and saving this much time in almost every question means a higher attempt and higher accuracy.
So, be sure to spend time learning equivalent fraction & percentages from 1/1 to 1/30.
