Answers :
1) Answer: E
Profit ratio of A, B and C = 4000 * 12:6000 * 6:4500 * 6
= 16:12:9
C’s profit share = 9/37 * 18500 = Rs.4500
2) Answer: A
Profit share of A, B and C = 4x * 12:5x * 12:(2x * 4 + (2x + 1600) * 8)
(4x * 12) /(24x + 12800) = 12/7
24x + 12800 = 28x
4x = 12800
x = 3200
A’s investment = 3200 * 4 = 12800
3) Answer: A
Initial investment of A = 4x
Initial investment of B = 4x * 125/100 = 5x
Profit ratio of A and B = (4x * 8 + (4x + 2000) * 4):(5x * 12) = 8:9
According to the question,
(32x + 16x + 8000) / (5x * 12) = (8 / 9)
(32x + 16x + 8000) * 9 = 8 * (5x * 12)
432x + 72000 = 480x
x = Rs.1500
Required Difference = Rs.1500
4) Answer: B
Ratio of the Renu and Rathika = (12000 * 4x):(8000 * 5x)
= 48:40
= 6:5
Profit share of Rathika = 5/11 * 22000 = Rs.10000
5) Answer: A
Profit share ratio of Bheem and Chukki = 3 * 10:1 * 8
= 15:4
Total profit of the business = 19/15 * 6000 = Rs.7600
