From May 1 to May 30 in the same year, the balance in a checking account increased. What was the balance in the checking account on May 30?

1) If during this period of time, the increase in the balance in the checking account had been 12%, then tha balance in the account on May 30 would haven been $504. 2) During this period of time, the increase in the balance in the checking account was 8% CEO Joined: 29 Mar 2007 Posts: 2591 Followers: 16 Kudos [?]: 234 [0], given: 0 Re: DS: checking account [#permalink] 05 Jun 2008, 12:07 puma wrote: From May 1 to May 30 in the same year, the balance in a checking account increased.

1.12x=504 --> we know the original amount, but by how much did it increase to?

2: insuff.

Together (1.08)*(504/1.12)

Suff.

C for me as well

from stat 1, you can find the original amount, but have no idea what the amount at the end of the month is

from stat 2, you know what the increase it, but not the original amount.

together, you have all you need

The answer can't to be A.

Sure, you can work backwards with 1.12x = 504, but that only gives you what you have in the beginning of the month. Nothing else in #1 says how much on an increase there is from May 1 to May 30, so we don't know by how much the balance increases.

#2 We don't know the starting balance, insufficient.

Together, we can work backwards with #1's info and then increase that balance by 8% with #2's info. Together they're sufficient.

What's the OA?

I thought C as well. The first statement only lets you solve backwords for the beg balance. The second statement says what % balance increased by. I thought maybe C trick, maybe the increase is not net of payments. I.e any account has an opening balance - payments+ deposits. but it says balance. which means total. it has to be C. Otherwise it would have to be E can someone shed light how the OA is A?

Forget it and move on. You know your reasoning is correct. That's the point of these anyway! ca_gold wrote: Hi Guys, I tried to answer this question before i read you replies. I thought C as well.
