Answer:
1:1:1
A=12, B=8, C=6. Ratio = (20*12) : (30*8) : (40*6) = 240 : 240 : 240 = 1 : 1 : 1.

X invests Rs. 60000 for 12 months. Y invests Rs. 90000 for 8 months. Z invests Rs. 120000 for 6 months. Profit ratio?
Answer:
1:1:1
Ratio = (60*12) : (90*8) : (120*6) = 720 : 720 : 720 = 1 : 1 : 1.

A, B and C invest Rs. 25000, Rs. 35000 and Rs. 45000. B gets 10% of profit for managing. Rest is distributed by capital. Total profit is Rs. 21000. Find B's total share.
Answer:
Rs. 8400
B's salary = 2100. Remaining profit = 18900. Ratio = 25:35:45 = 5:7:9. Total parts = 21. B's profit = (7/21)*18900 = 6300. Total B = 2100 + 6300 = Rs. 8400.

A and B invest in ratio 3:7. A's time is 14 months. Profit ratio is 1:2. B's time?
Answer:
12 months
Let B's time be t. (3 * 14) / (7 * t) = 1/2 => 42 / 7t = 1/2 => 84 = 7t => t = 12 months.
4665
P, Q, R invest in ratio 4:5:7. R gets Rs. 6000 more than P. Total profit?
Answer:
Rs. 36000
R - P = 7 - 4 = 3 parts. 3 parts = 6000 => 1 part = 2000. Total profit = 16 parts = 16 * 2000 = Rs. 32000.
4666
A and B invest Rs. 40000 and Rs. 50000. A withdraws Rs. 10000 after 6 months. B adds Rs. 10000 after 6 months. Profit ratio?
Answer:
7:11
A = (40*6) + (30*6) = 420. B = (50*6) + (60*6) = 660. Ratio = 420 : 660 = 42 : 66 = 7 : 11.
4667
A starts with Rs. 18000. B joins after 4 months with Rs. 27000. C joins after 6 months with Rs. 36000. Profit ratio?
Answer:
1:1:1
A=12, B=8, C=6. Ratio = (18*12) : (27*8) : (36*6) = 216 : 216 : 216 = 1 : 1 : 1.
4668
X invests Rs. 50000 for 12 months. Y invests Rs. 75000 for 8 months. Z invests Rs. 100000 for 6 months. Profit ratio?
Answer:
1:1:1
Ratio = (50*12) : (75*8) : (100*6) = 600 : 600 : 600 = 1 : 1 : 1.
4669
A, B and C invest Rs. 20000, Rs. 30000 and Rs. 40000. A gets 25% of profit for managing. Rest is distributed by capital. Total profit is Rs. 18000. Find A's total share.
Answer:
Rs. 7500
A's salary = 4500. Remaining profit = 13500. Ratio = 2:3:4. Total parts = 9. A's profit = (2/9)*13500 = 3000. Total A = 4500 + 3000 = Rs. 7500.

A and B invest in ratio 5:8. A's time is 16 months. Profit ratio is 1:1. B's time?
Answer:
10 months
Let B's time be t. (5 * 16) / (8 * t) = 1/1 => 80 / 8t = 1 => 8t = 80 => t = 10 months.
