A. 100%
B. 160%

I would ask to Gmatclub if this one is a really tough problem and if this is the standard on real Gmat ...

Thanks

Not to sound like a braggart, but I did this in my head in about 30 seconds, and wound up arriving at the correct answer fairly easily. Of all the 700 level gmat questions I have seen in the past, the vast majority of them definitely require me to at least put pen to paper, and usually take me 1:30-2 mins to solve, some times even longer (as in the case of a few of the gmat club questions). To me personally, that doesn't seem indicative of a 700 level question on the actual exam based on what I have heard and seen thus far, but then again, what do I know :) ?

I don't think it's a 700 level question. If you pick some smart number you'd be able to solve it quite easily.

Say Vartan's wages last week were $100, so he spent 0.15*100=$15 on recreation;
This week's wages is 0.9*100=$90, so he spends 0.3*90=$27 on recreation;

27/15=1.8, hence the amount he spends on recreation this week is 180% of the amount he spent on recreation last week: 15*1.8=27.

Answer: C.

What this question is testing is the concept of percentage decrease and the application of the formula new-old/ old or you could also you old-new/old

10(.15) - $1.5
10(.9) =$9 dollars in wages this week
$9(.3) = 2.7

2.7-1.5/1.5 = 80% increase which is 180% of the amount he spend last week- don't confuse with a "180% increase" those are two different things. This is more likely a 600 level question.

Thus

We can let the total wages last week = 100.

Thus, Varten spent 0.15 x 100 = 15 dollars on recreation last week.

Since his wages this week are 10 percent less than last weekʼs wages, this week’s wages are 0.9 x 100 = 90.

Thus, Varten spent 0.3 x 90 = 27 dollars on recreation this week.

The amount he spends on recreation this week is 27/15 = 9/5 = 1.8 = 180% of the amount he spent on recreation last week.
