Expert's post
An intuitive approach, with few or no written equations, might prove useful here.

The question is asking how many bushels of apples Steve picked yesterday, and the statements mostly just tell us about money, with no mention of the variable y used in the stimulus.

1) If Steve was paid $180 yesterday, he might have gotten paid$180 for one bushel, or $90 each for two bushels, etc. Insufficient. 2) Steve's total of$240 represents 10 more bushels than yesterday. Ignoring statement 1 for the moment, this means that today he could have picked 12 bushels @20 each, 80 bushels at $3 each, etc. The only real difference between this information and that offered in statement 1 is that we know he picked at least 10 apples today. Since that just tells us he picked at least 0 apples yesterday, that's not exactly revealing information. Insufficient. 1&2) Putting the two statements together, we know that the 10 extra bushels Steve picked today were worth$60 in pay. But is this at the rate of y or 1.5y? We don't have to do the calculations to know that we will get two different results. Insufficient.

I hope this helps those looking for a shortcut!

it is E, but it took good amount of time for me. Any shortcuts ?

Assume x > 42, two eq.
180 = 42y + (x-42)*1.5y
240 = 42y + (x-32)*1.5y
this will give y = 4 and x = 44

Assume x < 42
180 = xy
240 = (x+10)y
y = 6
x = 30

I got solution on this link
http://www.beatthegmat.com/picking-apples-t70206.html
but no shorcuts
even i am searching for the shortcut this question seemed quite time consuming i guess its a 750-800 level question

1. Yesterday, Steve was paid $180 for the apples he harvested. 2. Today, Steve was paid$240, and he harvested 10 more bushels of apples than he harvested yesterday.

actually...very simple to find out...
1. 180 might have been for 10 bushels or 180 might have been for 50 bushels for ex. - not sufficient.
2. clearly alone not sufficient.

1+2.
we have a difference of 60$for 10 bushels. we can have 2 options: 1. he sold yesterday 30 bushels for 60$/bushel, thus, today he sold 40 bushels and got 240$2. he sold yesterday 42+smth, and now he sold 42+smth+10 and got +60$.

2 outcomes - answer is E.
