A, B and C invest Rs. 10000, Rs. 15000 and Rs. 20000. C gets 10% of profit for managing. Rest is distributed by capital. Total profit is Rs. 13500. Find C's total share.
Answer:
Rs. 6750
C's salary = 1350. Remaining profit = 12150. Ratio = 2:3:4. Total parts = 9. C's profit = (4/9)*12150 = 4*1350 = 5400. Total C = 1350 + 5400 = Rs. 6750.

A and B invest in ratio 3:5. A's time is 8 months. Profit ratio is 1:2. B's time?
Answer:
9.6 months
Let B's time be t. (3 * 8) / (5 * t) = 1/2 => 24 / 5t = 1/2 => 48 = 5t => t = 9.6 months.

P, Q, R invest in ratio 5:6:7. Q gets Rs. 1800. What is the total profit?
Answer:
Rs. 5400
Ratio = 5:6:7. Q's share = 6 parts = 1800 => 1 part = 300. Total profit = 18 parts = 18 * 300 = Rs. 5400.

A and B invest Rs. 15000 and Rs. 25000. After 6 months A adds Rs. 5000 and B adds Rs. 5000. Profit ratio at the end of the year?
Answer:
7:11
A = (15*6) + (20*6) = 210. B = (25*6) + (30*6) = 330. Ratio = 210 : 330 = 7 : 11.

A starts a business with Rs. 25000. B joins after 4 months with Rs. 40000. C joins after 8 months with Rs. 50000. Find the profit ratio.
Answer:
15:16:10
A=12, B=8, C=4. Ratio = (25*12) : (40*8) : (50*4) = 300 : 320 : 200 = 15 : 16 : 10.

X, Y and Z invest in a business. X invests Rs. 20000 for 12 months. Y invests Rs. 30000 for 8 months. Z invests Rs. 40000 for 6 months. What is the ratio of their profits?
Answer:
1:1:1
Ratio = (20*12) : (30*8) : (40*6) = 240 : 240 : 240 = 1 : 1 : 1.
4687
A, B and C invest Rs. 6000, Rs. 8000 and Rs. 10000. A gets 20% of profit for managing. Rest is distributed by capital. Total profit is Rs. 7500. Find A's total share.
Answer:
Rs. 3000
A's salary = 20% of 7500 = 1500. Remaining profit = 6000. Ratio = 6:8:10 = 3:4:5. Total parts = 12. A's profit = (3/12) * 6000 = 1500. Total A = 1500 + 1500 = Rs. 3000.
4688
A and B invest in ratio 3:4. If they share profit in ratio 1:2 and A invested for 8 months, for how many months did B invest?
Answer:
12 months
Let B's time be t. (3 * 8) / (4 * t) = 1/2 => 24 / 4t = 1/2 => 6 / t = 1/2 => t = 12 months.
4689
P, Q, R invest in ratio 4:5:6. R gets Rs. 4000 more than P. Find total profit.
Answer:
Rs. 30000
R - P = 6 - 4 = 2 parts. 2 parts = 4000 => 1 part = 2000. Total profit = 15 parts = 15 * 2000 = Rs. 30000.

A and B invest Rs. 15000 and Rs. 20000. A withdraws Rs. 5000 after 6 months. B adds Rs. 5000 after 6 months. Profit ratio?
Answer:
5:9
A = (15*6) + (10*6) = 150. B = (20*6) + (25*6) = 270. Ratio = 150 : 270 = 15 : 27 = 5 : 9. Let me check my options. 5:9 is not there. Let's provide 5:9 in Option C.
