You can put this solution on YOUR website!
For every 5 invested by A, there was 7 invested by B, and 8
invested by C,
for a total investment of 5%2B7%2B8=20.
The ratio of total investment to A's investment is 20%3A5=4%3A1,
meaning that the total money invested in the partnership is 4 times A's investment.
The total profit must be 4 times A's profit, or
4%2A42360=highlight%28169440%29

NOTE: Those commas in your multiple choice answers puzzle me.
Either they are misplaced or there is a strange use of commas in your country that I have never seen before.
The problem mentioned a profit of 43260, without any commas.
Some countries use a comma to separate the integer part of a number from the decimal part, so they would have at most one comma in a number.
Other countries use a dot to separate the decimal part, but use commas to separate digits in groups of three, so that 10 million dollars and 5 cents would be $10,000,000.05.
