This is going to this question: a-4-cm-cube-is-cut-into-1-cm-cube-what-is-the-percentage-37027.html?fl=similar
Don't want to repost it, since it seems to have been discussed many many times.
I understand the calculations, don't understand the reasoning for calling a 4-fold increase as an increase of 300% rather than 400. As I read that question, I take it to mean "how many fold did this increase" rather than "by how much did it increase". Am I just not reading the question correctly? Misinterpreting the keywords?
two fold of something ===> twice of something
three fold of something====> thrice of something
four fold of somthing ===> four times of something
lets take any value X....==> FOUR FOLD OF X will be four times of X= 4X
Now if calculate percent increase then
((4X-X)/X)*100= 300 %
Hope it helps...
