A.
N5000 
B.
N1800 
C.
N12000 
D.
N24000 
E.
N8000
Correct Answer: Option C
Explanation
A : B = 3 : 5
Total ratio = 3 + 5 = 8
Let rept, the total profit, A receives (frac{3x}{8})
(frac{5x}{8}) – (frac{3}{x}) = 3000
(frac{5x}{8}) – (frac{3x}{8}) = 3000
= (frac{2x}{8})
= 3000
2x = 2400
x = 1200
N12,000
