A, B and C start a small business. A contributes 1/5th of the total capital invested in the business. B contributes as much as A and C together. Total profit at the end of the year was $5,200. What was C's profit share?
A. 1500
B. 1510
C. 1560
D. 2510
E. 2700
Since B equals the total of A and C, we can say that B is half of the total of A, B and C
Also, A is 1/5th of the total
Thus, it is best to assume the total of A, B and C to be a multiple of 2 and 5 (denominators) = 10
Thus: A = 10/5 = 2 and B = 10/2 = 5; hence C = 3
Ratio of A, B and C = 2 : 5 : 3
Thus, C = 5200 x 3/10 = 1560
Alt:
Since B equals the total of A and C, we can say that B is half of the total of A, B and C = 5200/2 = 2600
Also, A is 1/5th of the total = 5200/5 = 1040
Thus, C = 5200 - (1040 + 2600) = 1560
