RATIO AND PROPORTION SHORTCUTS FOR QUANTITATIVE APTITUDE o RATIO - the ratio of two quantities of the same kind is the fraction that one quantity is of the other, in other words to say, how many times a given number is in comparison to another number. A ratio between two nos.x A and B is denoted by A/B o Some of the points to be remembered : 1. The two quantities must be of the same kind. 2. The units of the two quantities must be the same. 3. The ratio has no measurement. 4. The ratio remains unaltered even if both the antecedent(A) and the consequent(B)are multiplied or divided by the same no. o If two different ratios ( say A /B and C/D) are expressed in different units, then if we are required to combine these two ratios we will follow the following rule= A xC / B xD The required ratio is AC / BD o The duplicate ratio ...
