We look for the difference between the starting value AND the end value OVER the initial value. Both.

Workers \(\frac{20-10}{20}= 0.5\)

\(\frac{50-5}{5} = 9\)

\(\frac{9-0.5}{0.5} = \frac{90-5}{5} = 17\)

D is the answer without bother yourself to multiply * 100.

Hope this helps

This seems wrong, your approach is looking for the percentage change.

When we use the word "Greater" , we are looking for the ratio

@Carcass
Please help.



The question asks us
. The percent increasein the pay of Megalomania’s CEO from 1990 to 2000 was what percent greater than the percent the decrease in the hourly pay of Megalomania’s factory workers over the same period

so percent increase--- how much % greater-- than percent decrease..

The portion after than is in the BASE, so 50 is in the base....
Percent increase and percent decrease are positive, so 100*(900-50)/50..

Also Carcass has explained the method above

The last collection of questions for the GRE Quant - 2019




At Megalomania Industries, factory workers were paid $20 per hour in 1990 and $10 per hour in 2000. The CEO of Megalomania Industries was paid $5 million per year in 1990 and $50 million per year in 2000. The percent increase in the pay of Megalomania’s CEO from 1990 to 2000 was what percent greater than the percent the decrease in the hourly pay of Megalomania’s factory workers over the same period?

A) 850%

B) 900%

C) 950%

D) 1,700%

E) 1,900%


First, let’s calculate the percent decrease for the workers, using the formula (New - Old)/Old x 100:

(10 - 20)/20 x 100 = 50% decrease

Next we calculate the percent increase for the CEO:

(50,000,000 - 5,000,000)/5,000,000 x 100

45,000,000/5,000,000 x 100

9 x 100 = 900% increase

Thus:

(900 - 50)/50 x 100

850/50 x 100 = 1700%

Answer: D
