Hi yumi,
well it depends on the given! But assuming that the given is the following:
Interest rate compounded annually=10%
and the period is one year then the formula above would represent the balance after one year with interest compounded semi annually.
The GMAT can be destroyed.

You can use this formula to calculate compound interest:
Final balance = P( 1 + r/c)^nc where:
P = the principal (the initial investment)
r = the annual interest rate expressed as a decimal
c = the number of times the interest is compounded each year
n = the number of years the investment collects interest


Example:
Kevin invests $1300 at an annual interest rate of 8 percent compounded quarterly. What is the value of his investment after 7 years?
Final balance = P( 1 + r/c)^nc
= 1300(1 + 0.08/4)^(4x7)
= 1300(1.02)^28

Cheers,
Brent
