27000 * 1.5% = 405- commission for investment.

27 * 1000 * ( 1+0.04) * ( 1+0.045) * ( 1-0.0 1) * ( 1-0.025) = 28325.

28323.9 * 1.5% = 424.8- handling fee when selling.

28323.9 * 1% = 283.2- transaction tax at the time of sale.

28323.9-27000-405-424.8-283.2 = 210.9-Total income

So the total income is 2 10.9 yuan.
