Percentage increase $= 76.19%$

$210*x/100=370$

$rarr x=370/210*100=176.19%$

If the multiplication factor is $176.19%$ , then this is an increase of

$176.19% - 100% = 76.19%$ .

$76.2%$ to 2 dp

We use the same calculation to find any change as a percent. This can be an increase, decrease, profit, loss, mark-up, discount etc ..

First find the actual change: "Bigger - smaller"

To find the change as a percent:

$"change"/"original amount" xx 100%$

In this case, the change is: $370-210 = 160$

The original amount was $210$ which then increased to $370$

$160/210 xx 100%$

$= 76.19$
