by this conversion table we can change fraction into percentage and percentage into fraction
EX:- if we have to find 2/5 in %?
In the table we know that 1/5=20%
then, if we multiply both by 2
then we have 1/5x2 = 2x20%
answer is 2/5 = 40%
so, you only to know basic fraction and percentage that given above.
in the inverse
Ex. If we have to find out 1/15 fraction in percentage%?
then, if we multiply both by 2
then we have 1/5x2 = 2x20%
answer is 2/5 = 40%
so, you only to know basic fraction and percentage that given above.
in the inverse
Ex. If we have to find out 1/15 fraction in percentage%?
In the table we
have 1/5 = 20%
then both side
multiple by 1/3
we get 1/15 =
6.66%

SOME BASIC PERCENTAGE PROBLEMS TRICKS AND SHORTCUTS THAT IS ALWAYS ASKED
IN THE EXAMS
PROBLEM ON PERCENTAGE
TYPE 1.
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 ---- 50x50/100= 25% decrease/loss
TYPE 2.
if A is P% more than B. then B is less than by A
with P/(100+P)x100
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 ---- 50x50/100= 25% decrease/loss
TYPE 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%
TYPE 3.
If A is P% less
than B. then B is more than by A
with P/(100-P)x100
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%
TYPE 4.

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
CLICK HERE FOR ALL MATHS SHORTCUT TRICK CHAPTER WISE
ex. If petrol
price increase by 25%. How much percentage a person reduced his consumption so that
his expenditure on it does not increase?
ans. 25/(100+25)x100=20%
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
ex. If there is
30% decrease in eggs price. How much a person increased his consumption so that
his expenditure on it does not increase?
ans. 30/(100-30)x100=42.85
ans. 30/(100-30)x100=42.85
TYPE 6.
Ex. If suman need
36% minimum mark to passed a exam but she score 24% mark and fail by 9 marks. What
is the total mark?
ans. Difference in % = difference in mark
ans. Difference in % = difference in mark
In
that 36%-24%=12%
that is 12%=9marks
so, total mark = 9/12x100= 75
that is 12%=9marks
so, total mark = 9/12x100= 75
