Jill invests $10000 in an account that pays an annual rate of 3.96%, compounding semi-annually. Approximately how much does she have in her account after two years?

On the GMAT, you are not allowed to use a calculator, and yet the test can give you problems like this. It is so important to learn estimation skills that allow you to dispatch questions like this with simple arithmetic.

I don't know how I got this wrong.

3.96% = 0.0396

Then 1.0396^4 (4 semesters in 2 years) * 10^4 Then (10*1.0396)^4 So you get (10.396^4) as the answer. So answer should have 6 in last digit but I don't see any answer choice that fits the bill.

Dear J, What you thought was a clever approach, but you see, with money, folks always round everything to the nearest penny. That units digit might be in the tenths or hundreds or thousands of cent, so that just gets rounded off and does not appear in the monetary answers. In fact, three places after the decimal is the thousands place for the 6 in 10.396, so when we raise that to the fourth, the final 6 would be in the trillionth place, the 12th place after the decimal point. That's definitely a decimal place you will not see on your bank statement! Does all this make sense? Mike

Yeah got it Mike, that was very kind of you to clarify

Thanks

Cheers! J

PS. I guess one can use simple interest to solve cause the answer choices are quite spread between you can easily arrive at something near 8%
