how to find % of increase eg;last yr 900 rs this yr 1300rs pls reply?

Answer 1

The formula to find percent of increase is:

the amount of increase divided by the original amount

Therefore, in your problem, the amount of increase is 400 rs and the original amount is 900 rs.

400 divided by 900 as a percent is equal to 44.4% or 44 and 4/9 %

Answer 2

In order to calculate percent increased, you would just divide the first number by the second and multiply by 100%. Eg.:

1300/900 * 100%= 144%

just as if your sales doubled from 250 rs last year to 500 rs, then the percent increase would be 200%, right?
500/250 *100%= 200%

Answer 3

To find the percent change (increase or decrease) find the change between the original value and the current value and divide that by the original value. A simple way to remember it is "difference divided by original".

In your example, the difference, or change, is 1300 - 900 = 400. The original is 900... so divide 400 by 900. You'll get a decimal so multiply by 100 to change it to a percent.

The tricky part is remembering to divide by the original... if you divide by the ending value, you won't get the right answer. :-)
