X, Y and Z invest Rs. 18000, Rs. 24000 and Rs. 30000. Z gets 5% of profit for managing. Rest is distributed by capital. Total profit is Rs. 14400. Find Z's total share.
Answer:
Rs. 6420
Z's salary = 5% of 14400 = 720. Remaining profit = 13680. Ratio = 18:24:30 = 3:4:5. Total parts = 12. Z's profit = (5/12) * 13680 = 5 * 1140 = 5700. Total Z = 720 + 5700 = Rs. 6420.

A starts a business with Rs. 30000. B joins after 4 months with Rs. 40000. C joins after another 4 months with Rs. 50000. Find the profit ratio.
Answer:
9:8:5
A=12, B=8, C=4. Ratio = (30*12) : (40*8) : (50*4) = 360 : 320 : 200 = 36 : 32 : 20 = 9 : 8 : 5.

A, B and C enter into a partnership. A invests Rs. 5000 for 12 months, B invests Rs. 6000 for 8 months, and C invests Rs. 8000 for 5 months. If C gets Rs. 2000, what is the total profit?
Answer:
Rs. 7400
Ratio = (5000*12) : (6000*8) : (8000*5) = 60000 : 48000 : 40000 = 60 : 48 : 40 = 15 : 12 : 10. Total parts = 37. C's share is 10 parts = 2000 => 1 part = 200. Total profit = 37 * 200 = Rs. 7400.

P, Q, R invest in a business. P invests 1/5 of the total capital for 1/2 of the time. Q invests 1/3 of the total capital for 1/4 of the time. R invests the remaining capital for the whole time. Find the ratio of their profits.
Answer:
6:5:28
R's capital = 1 - (1/5 + 1/3) = 1 - 8/15 = 7/15. Profit ratio = (1/5 * 1/2) : (1/3 * 1/4) : (7/15 * 1) = 1/10 : 1/12 : 7/15. Multiply by 60: 6 : 5 : 28.

A and B invest Rs. 10000 and Rs. 12000. After 4 months A withdraws Rs. 2000 and B adds Rs. 3000. After another 4 months C joins with Rs. 15000. Profit ratio?
Answer:
26:42:15
A = (10*4) + (8*8) = 40 + 64 = 104. B = (12*4) + (15*8) = 48 + 120 = 168. C = 15 * 4 = 60. Ratio = 104 : 168 : 60 = 26 : 42 : 15. Wait, 168 / 4 = 42. Option A has 33. My bad: B adds 3000, so B becomes 15000. 12*4 = 48, 15*8 = 120. 48+120=168. C joins after 8 months, so C's time is 4 months. 15*4 = 60. Ratio 104:168:60 => 26:42:15. I will change option A to 26:42:15.

X starts a business with Rs. 15000. Y joins after 3 months with Rs. 20000. Z joins after 6 months with Rs. 30000. Find the profit ratio.
Answer:
1:1:1
X=12, Y=9, Z=6. Ratio = (15*12) : (20*9) : (30*6) = 180 : 180 : 180 = 1 : 1 : 1.
4697
A, B and C invest Rs. 2000, Rs. 3000 and Rs. 4000. B gets 20% of profit for managing. If total profit is Rs. 4500, what is B's total share?
Answer:
Rs. 2100
B's salary = 20% of 4500 = 900. Remaining profit = 3600. Ratio = 2:3:4. Total parts = 9. B's profit = (3/9) * 3600 = 1200. Total B = 900 + 1200 = Rs. 2100.
4698
P, Q and R invest in a business. P invests 3 times as much as Q. Q invests 1/4 of R. Total profit is Rs. 8000. What is P's share?
Answer:
Rs. 3000
Let R = 4x. Q = x. P = 3x. Ratio P:Q:R = 3:1:4. Total parts = 8. P's share = (3/8) * 11000 = 4125. Let me make profit Rs. 8000. P's share = 3000. I'll update profit to Rs. 8000.

M and N invest Rs. 50000 and Rs. 70000. M withdraws Rs. 10000 after 6 months. N adds Rs. 10000 after 6 months. Profit ratio?
Answer:
3:5
M = (50*6) + (40*6) = 540. N = (70*6) + (80*6) = 900. Ratio = 540 : 900 = 54 : 90 = 3 : 5.

A, B and C invest Rs. 8000, Rs. 12000 and Rs. 16000. A gets 12.5% of total profit for managing. Rest is shared by capital. If A's total share is Rs. 2300, what is the total profit?
Answer:
Rs. 7200
A gets 1/8 P. Rem = 7/8 P. Ratio = 8:12:16 = 2:3:4. Total parts = 9. A's profit share = (2/9)*(7/8)P = 14/72 P = 7/36 P. Total A = (1/8 + 7/36) P = (9+14)/72 P = 23/72 P. 23/72 P = 3100 => P = 9704. Let's adjust total profit to Rs. 7200. A's salary = 900. Rem = 6300. A's profit = (2/9)*6300 = 1400. Total A = 2300. I'll make A's share Rs. 2300.
