[CSAT][CAT] Basic Numeracy – Percentages – Base (Tips &Tricks) – 3
Regaining back from our last post : [CSAT][CAT] Basic Numeracy – Percentages – Concept (Tips & Tricks) – 2, now lets learn the concept of base of a percentage and how relevant it is in calculations of CAT & UPSC CSAT Prelims questions.
Base : So what do you think a base of a percentage should be ?
What does it infer ??Does it infer that 80 students have passed the exam.orDoes it infer that 0.80 students have passed the exam. (as we learned in our last article that 80% = 0.80)
Lets redefine this question by including a BASE.80% of the students of class 10th having a total strength of 340 from XYZ school have passed the CBSE Board exam.Now we have a BASE i.e. total strength of the class i.e 340.So if the total strength of class 10th in XYZ school were 34080% of 340 = (80/100) x 340 = 272 students passed the exam.
