Hi Gmat_mission,
We're told that a mutual fund averages 10% growth annually for the first three years, but it loses 30% of its value in the fourth year. We're asked for the value of the mutual fund, at the end of 4 years, is approximately what percent of the amount originally paid for it. This question can be solved in a couple of different ways, including by TESTing VALUES.
IF... the original purchase price of the fund was $100...
then the value at the end of the 1st year was $100 + (.1)($100) = $110
then the value at the end of the 2nd year was $110 + (.1)($110) = $121
then the value at the end of the 3rd year was $121 + (.1)($121) = $133.10
and the value at the end of the 4th year was approximately $133 - (.3)($133) = $133 - $39.90 = approximately $93
$93 out of the original $100 is 93/100 = 93%
Final Answer: A
