The investment is doubled very succeeding year for 5 yrs.

1st yr - 10
20
40
80
5th yr - 160

Total investment = 10 + 20 + 40 + 80 + 160 = 310

%age investment in first yr = 10/310 *100 = 100/31 = 3% approx

I think you should post the source (GMAT Club Challenge) of this problem so it can be tagged to the master forum...
