Question

How to solve percentage, simple interest and perimeter

Answer 1

Answer:

Percentage means the no., amount etc.

i.e 1/100 of anything

To solve it

Example find the 50% of 500

as we have given the number 50/100 i.e 50%

we can Do it like

50/100×500

= 250

to find the simple interest we have a common formula that is p×r×t/100

where p=principle i.e amount

r= rate

t = time

perimeter is easily the sum of all sides whether it is a circumference of a circle or are all sides of a square
