Percentage sounds as being one of the simplest topics as, conceptually it is very easy to understand. But real fight is in its application. Questions directly on percentage are only asked in Banking exams or SSC exams but when it comes to MBA Entrance examinations, the concept and calculations are applied in other long questions.
A percent is a ratio whose consequent is 100.
• ‘Percent’ comes from the Latin phrase per centum, which means per hundred
• % is used as the symbol for percent
When we say that ‘x is p% of y’ we mean that x : y :: p : 100
For example, ‘My income is 20% of yours’ means that
my income : your income :: 20 : 100
As ratios can be represented by fractions or numbers (decimals), so percent can also be represented by fractions or numbers (decimals). Several combinations of conversions are possible.
