Average cost of water for each household= 75/120;
Average cost of water after increase = 80/120;

percent increase = (5/120 / 75/120 )* 100 = 1/15 * 100 = 6.66

~ 7%

I'm pretty sure that you don't even need to know what the cost per household is, since the amount of households remains the same for the problem. All you need to know is that the cost increases from 75,000 to 80,000. So, the percentage increase is equal to 5,000/75,000, which equals .0666, or ~7.

Exactly Same. I saw this problem today in my PR CAT1.
PR math is easier than GMATPrep. I got 36 correct in PR.

The only somewhat accurate adaptive CAT is the GMATPrep. No test prep company can decipher the scoring algorithm that PVue uses.

That is so true.
