Mega Watts not lost (2000 - 90) = 1910
2000 Mega Watts represents = 100%
:. 1910 Mega Watts represents = 100/2000 * 1910
=95.5%
percentage of the generated power reaches its destination =95.5%

The question is:
"What percent of 2000 is 1910?"
1910 is 2000 minus the 90 megawatts lost.
n% * 2000 = 1910
n/100*2000=1910
n*20=1910
n = 1910/20
n = 95.5%

90 divided by 2000
90/2000 = .045 , or 4.5% is lost, which means 95.5 percent makes it to the destination.
