Explanation
50 as a percent of 30 is \(\frac{50}{30} \times 100\)% = 166.6%.
(Note: it’s incorrect to calculate “50 percent of 30,” which is 15. This asked for 50 as a percent of 30, which is equivalent to asking, “What percent of 30 is 50?”)
To find the percent increase from 30 to 80, use the percent change formula:
Percent Change = \(\frac{Difference}{original} \times 100\)%
Percent Change = \(\frac{80-30}{30} \times 100\)% = 166.6%
The two quantities are equal. Note that doing the final calculation in each quantity is not necessary, because both equal \(\frac{50}{30}\times 100\).
50 as a percent of 30 is \(\frac{50}{30} \times 100\)% = 166.6%.

Quantity A = 50/30 *100%
Quantity B = (80-30)/30*100% = 50/30*100%
--> A = B
--> C
Quantity B = (80-30)/30*100% = 50/30*100%
--> A = B
--> C
