SOME BASIC PERCENTAGE PROBLEMS TRICKS AND SHORTCUTS THAT IS ALWAYS ASKED IN THE EXAMS
PROBLEM ON PERCENTAGE
if there is increase of X% and subsequently X% decrease then there is always loss / decrease in the condition.ex. If rohan salary is increase by 50% and subsequently decrease by 50%. How much percentage loss?ans. By trick —- 50×50/100= 25% decrease/lossTYPE 2.
if A is P% more than B. then B is less than by A
with P/(100+P)x100
ex. If radha earning is 25% more than sita. Then sita earning is how many percentage less then by radha?ans. By trick —- 25/(100+25)x100=20%
with P/(100-P)x100
ex. If golu age is 20% less than gita than gita age is how many percentage more than golu?
ans. By trick —- 20/(100-20)x100=25%
if there is p% increase in price . how much % decrease his consumption so that his expenditure on it does not change.
formula P/(100+P)x100
ans. 25/(100+25)x100=20%
TYPE 5.
if there is p% decrease in price . how much % increase his consumption so that his expenditure on it does not change.
formula P/(100-P)x100
ans. 30/(100-30)x100=42.85
TYPE 6.
ans. Difference in % = difference in mark
that is 12%=9marks
so, total mark = 9/12×100= 75
