GWD 24-16

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 percent, then the balance in the account on May 30 would have been $504

(2)   During this period of time, the increase in the balance in the checking account was 8 percent.

The answer is A, but I think it is C

From (1)  X * 1.12 = 504     X is known

Then from  (2)  X *1.08=Answer

Therefore, I think the answer is C.

Please help me. Thanks a lot.

答案是C

这道题如果原文没错的话就应该是A
