Amount is going to be double. as it is simple interest so 15*6=90%
invested in the mid of jan so int for the month of jan is 7.5%
so by the end of july he will have 97.5% returns and in the month of august he will get 15% more
so the answer is august

Here he invested $100 in mid of January in a fund,which earn 15% interest every month
i.e Simple interest every month = $15
Now at the end of 6th month i.e July, the fund will have = (15*6) +100 = $90 +$100 =$190 (we have add $100, because we are calculating SI)
Therefore in the Month of August he will have = 190 +15 = $205 , hence it is more than $200
