New Profit = 7% of 100x = 7x i..e. Now A's profit = (2/3)*7x
Change in A's profit = (2/3)*7x - (2/3)*5x = (4/3)x
Given, (4/3)*x = $400
i.e. x = $300
B's profit = (1/6)*7x = 7*300/6 = $350
Answer: Option C

a. $600 b. $850 c. $350 d. $1100 e. $2100

let profit be x so for A given profit is 2/3 it receives so 1.07x*2/3-1.05x*2/3 = 400 or say 2x*.02 =1200 x= 30,000 now we need to determine profit of B @ 7% so 0.07*30,000 * 1/3* 1/2 = 350$ IMO C

I did not assume value of interest like in your case , i solved using variables not sure where i got solution wrong please advise..
There are more than one mistake
if x is the profit in first case then 1.05x has no meaning as x itself must be 5% of cost that's why I started with assumption of cost as 100x and not profit.
second mistake is that the initial profit sharing of B is not what question is asking. Question is asking the later profit sharing of B
i.e. 0.07x is the profit in later case as per your calculation assuming that x is the cost
0.07x*(1/3)*(1/2) is teh profit sharing of B = (7/100)*(1/6)*30000 = $350

In order to determine the ratio in which the profit is split, we can assume a simple number to be the total profit. Let that be $300 - A will receive \(\frac{2}{3}*300 = $200\) B and C get an equal share of the remaining $100. Ratio of profits is 4:1:1
We are told that for a 2% increase in profit, the income of A increases by $400. Tthe total income of the partners increases by $600(ratio is 4:1:1). The total amount on which the profit is generated is \(\frac{$600}{2}*100 = $30000\).
Therefore, the total profit that B takes home is \(\frac{1}{6}*\frac{7}{100}*30000\) = $350(Option C) _________________
