Manish:
151% increase DOES NOT mean multiplying a number by 1.51, it means
multiplying by 2.51. Check it for yourself:

Take a simple example: 150% increase from 2 means doubling 2 one time and
then adding another 50%... obtaining 2+2+1=5. My answer would provide the
right answer, or 2*(150%+1)=2*(1.5+1)=2*2.5=5. Your answer would only yield
3.

Look at the formula you gave for #1, 3700/(100%-11.60%). You have to do the
same thing for increases... you only had 4500/151%, you need
4500/(100%+151%)=4500/(2.51)

David,

Dan's response proves that I was right in dividing 4500/151%. Dan was
looking for 151% increase and not 251% increase.

Dan,

It is my pleasure.

Why do you worry for future, when we guys are here to help you out.

The answer for #2 is wrong, you forgot to add a 1 to the 151%. The formula is:
4500/2.51

Dan, answers to your examples are as under:

1. This years sales are $3700, a decrease of 11.6%. Last years
sales would be $4185.52.

Formula : =3700/(100%-11.60%)

2.This years sales are $4500, an increase of 151%. Last years
sales would be $2980.13

Formula : 4500/151%

Thanks,

Hello -
My algebra days seem to be a little hazy today. Could someone please
assist on the basic calculation to find the original number.

example 1:
This years sales are $3700, a decrease of 11.6%. What would last years
sales be?

example 2:
This years sales are $4500, an increase of 151%. What would last years
sales be?

Thanks for any insight on this calculation.
Dan
