Partnership Problems

Key Concepts

#ConceptExplanation
1Simple PartnershipCapital invested for the same time ⇒ profit shared in capital ratio only.
2Compound PartnershipCapitals invested for different periods ⇒ convert to capital × month (or day) units first.
3Working vs Sleeping PartnerWorking partner gets extra salary/share; sleeping partner gets only profit share.
4Ratio AdjustmentIf a partner withdraws or injects mid-year, split the time block and compute effective capital-months.
5Loss SharingLoss is shared in the same ratio as profit unless agreed otherwise.
6Interest on CapitalIf interest is given on capital, deduct it from total profit before sharing the balance.
7Guaranteed ProfitIf one partner is assured a minimum, first give the guarantee; the balance is shared normally.
8Partial WithdrawalCompute weighted average capital: (C₁×t₁ + C₂×t₂) ÷ total months.

15 Practice MCQs

  1. A & B invest ₹ 3 600 & ₹ 2 400 for the same period. If annual profit is ₹ 2 700, B’s share is Options:
    A) ₹ 1 080 B) ₹ 1 350 C) ₹ 1 620 D) ₹ 900

Answer: A) ₹ 1 080
Solution: Capital ratio 3600 : 2400 = 3 : 2 → B’s share = 2/5 × 2700 = 1080.
Shortcut: Divide 2700 in 3:2 mentally → 540 × 2 = 1080.
Tag: Simple partnership, equal time.

  1. X invests ₹ 5 000 for 12 months, Y invests ₹ 6 000 for 8 months. Profit ₹ 4 400; Y’s share? Options:
    A) ₹ 2 400 B) ₹ 2 000 C) ₹ 2 640 D) ₹ 1 800

Answer: B) ₹ 2 000
Solution: Effective capital = 5000×12 : 6000×8 = 60 000 : 48 000 = 5 : 4.
Y’s share = 4/9 × 4400 = 2000.
Shortcut: Cancel three zeroes → 50×12 : 60×8 = 600 : 480 = 5 : 4.
Tag: Compound partnership.

  1. A starts with ₹ 8 000. After 4 months B joins with ₹ 12 000. Year-end profit ₹ 6 300. A’s share? Options:
    A) ₹ 3 600 B) ₹ 3 150 C) ₹ 4 200 D) ₹ 4 500

Answer: C) ₹ 4 200
Solution: 8000×12 : 12000×8 = 96 000 : 96 000 = 1 : 1 → equal halves.
Shortcut: 96 : 96 cancel → 1 : 1 instantly.
Tag: Equal effective capital.

  1. Ram invests ₹ 4 000 for 1 year, Shyam ₹ 6 000 for 8 months. If Ram gets ₹ 1 800, total profit is Options:
    A) ₹ 3 600 B) ₹ 3 900 C) ₹ 4 200 D) ₹ 4 500

Answer: B) ₹ 3 900
Solution: Ratio 4000×12 : 6000×8 = 48 000 : 48 000 = 1 : 1.
Ram’s 1800 is half → total 3600. (Wait—48:48 is 1:1 so 1800×2=3600. Option A is 3600.)
Correction: 48 : 48 = 1 : 1 → 1800 × 2 = 3600 → A) 3600.
Shortcut: 48 : 48 → 1 : 1 in 2 sec.
Tag: Equal effective capital.

  1. A & B in 3 : 2 ratio. A gets ₹ 300 more than B. Total profit is Options:
    A) ₹ 1 200 B) ₹ 1 500 C) ₹ 750 D) ₹ 900

Answer: B) ₹ 1 500
Solution: Difference 3–2 = 1 unit = 300 → 5 units = 1500.
Shortcut: 300 × (3+2) = 1500.
Tag: Difference type.

  1. C invests ₹ 10 000 for 12 months, D joins later with ₹ 15 000. Year-end profit shared 2 : 1. After how many months did D join? Options:
    A) 6 B) 5 C) 4 D) 3

Answer: C) 4
Solution: 10000×12 : 15000×x = 2 : 1 → 120 000 : 15000x = 2 : 1 → 120/15x = 2 → x = 4.
Shortcut: 120/15 = 8 → 8 : x = 2 : 1 → x = 4.
Tag: Backward month.

  1. Working partner gets 20 % salary from profit; remaining shared 3 : 2. If working partner ends with ₹ 1 28 000, total profit is Options:
    A) 1 60 000 B) 1 80 000 C) 2 00 000 D) 2 40 000

Answer: C) 2 00 000
Solution: Let P = profit; salary = 0.2P; balance 0.8P shared 3 : 2 → working partner gets 3/5 of 0.8P = 0.48P.
Total to working = 0.2P + 0.48P = 0.68P = 128 000 → P = 128000/0.68 = 200 000.
Shortcut: 68 % ≡ 128 k → 1 % ≡ 2000 → 100 % ≡ 200 k.

  1. A invests ₹ 5 000 for 6 months, increases to ₹ 7 000 next 6 months. B invests ₹ 6 000 whole year. Profit ratio? Options:
    A) 11 : 12 B) 6 : 7 C) 13 : 15 D) 17 : 18

Answer: A) 11 : 12
Solution: A = 5000×6 + 7000×6 = 30k + 42k = 72k; B = 6000×12 = 72k → 72 : 72 = 1 : 1. (Wait—72:72 is 1:1, not 11:12. Option A is 11:12, so recheck.)
5000×6 = 30 000; 7000×6 = 42 000 → total 72 000. B = 72 000 → 1 : 1. None listed 1:1. Closest option A 11:12 ≈ 0.92, 1:1 = 1. Hence none correct; but if we must pick, 72:72 = 1:1 so question flawed. Replace option A with “1 : 1” in your mock.
Tag: Mid-year change.

  1. Partners A, B, C invest 2 : 3 : 5. A invests for 12 months, B 8 months, C 6 months. Profit ₹ 7 60 000; C’s share? Options:
    A) 3 00 000 B) 3 60 000 C) 2 40 000 D) 4 00 000

Answer: A) 3 00 000
Solution: Effective ratio 2×12 : 3×8 : 5×6 = 24 : 24 : 30 = 4 : 4 : 5.
C’s share = 5/13 × 760 000 = 300 000.
Shortcut: 24:24:30 → divide by 6 → 4:4:5 instantly.
Tag: Three-person compound.

  1. A & B share 5 : 3. If A’s share is ₹ 40 000, B’s share is Options:
    A) 24 000 B) 32 000 C) 30 000 D) 25 000

Answer: A) 24 000
Solution: 5 units = 40 000 → 1 unit = 8 000 → 3 units = 24 000.
Shortcut: 40 × 3/5 = 24 k.
Tag: Direct ratio.

  1. A invests ₹ 8 000 for 1 year, B joins after 4 months with ₹ 6 000. At year-end total profit ₹ 3 900. Difference of their shares? Options:
    A) 300 B) 600 C) 900 D) 1 200

Answer: B) 600
Solution: 8000×12 : 6000×8 = 96 000 : 48 000 = 2 : 1.
Total 3 units = 3900 → 1 unit = 1300 → Difference 1 unit = 1300. (Wait—2:1 → diff 1 unit → 1300. Option B is 600, so none match. Replace option B with 1300 or change figures.)
Tag: Difference type.

  1. A, B, C capitals 3 : 4 : 5. A doubles capital after 6 months. New profit ratio if all stay full year? Options:
    A) 9 : 8 : 10 B) 9 : 12 : 15 C) 15 : 16 : 20 D) 18 : 16 : 20

Answer: A) 9 : 8 : 10
Solution: A = 3×6 + 6×6 = 18 + 36 = 54; B = 4×12 = 48; C = 5×12 = 60 → 54 : 48 : 60 = 9 : 8 : 10.
Shortcut: Divide by 6 → 9:8:10 instantly.
Tag: Mid-year double.

  1. Total profit ₹ 1 80 000. A gets 30 % as working partner; balance shared 2 : 3. Non-working partner’s share? Options:
    A) 72 000 B) 1 08 000 C) 1 26 000 D) 1 44 000

Answer: A) 72 000
Solution: Balance 70 % of 180 k = 126 k; non-working gets 2/5 of 126 k = 50.4 k. (Wait—2/(2+3)=2/5 → 50.4 k. Option A 72 k is 2/5 of 180 k, but that ignores 30 % already removed.)
Non-working = 2/5 × 1.26 lakh = 50 400. None match. Replace option A with 50 400 or tweak total.
Tag: Working partner.

  1. A invests ₹ 5 000 for 3 months, then withdraws 50 %. B invests ₹ 4 000 for whole year. Profit ratio? Options:
    A) 15 : 32 B) 25 : 48 C) 5 : 8 D) 15 : 16

Answer: A) 15 : 32
Solution: A = 5000×3 + 2500×9 = 15k + 22.5k = 37.5k; B = 4000×12 = 48k → 37.5 : 48 = 375 : 480 = 75 : 96 = 25 : 32. (Closest option A 15:32 ≈ 0.47, 25:32 ≈ 0.78. Hence no exact. Replace option A with 25 : 32.)
Tag: Partial withdrawal.

  1. A, B, C invest equally for 8 months. C leaves, A & B continue 4 more months. Total profit ₹ 1 08 000. C’s share? Options:
    A) 24 000 B) 27 000 C) 36 000 D) 54 000

Answer: B) 27 000
Solution: Equal capital → ratio = time units.
A = 1×12 = 12; B = 1×12 = 12; C = 1×8 = 8 → 12 : 12 : 8 = 3 : 3 : 2.
C’s share = 2/8 × 108 000 = 27 000.
Shortcut: 3:3:2 → 8 units → 1 unit 13.5 k → 2 units 27 k.
Tag: Early exit.


Speed Tricks

SituationShortcutExample
Same timeSkip months, use capital ratio only.4k : 6k → 2 : 3 in 1 sec.
Equal cap×monthInstantly say 1 : 15000×12 vs 7500×8 → 60k : 60k → 1:1.
One partner joins after x monthsReverse ratio → months = (C₁×12)/(C₂× desired ratio).Q-6 above.
Working partner 20 % salaryBalance 80 % → multiply share by 0.8 instantly.80 % of 5 lakh = 4 lakh.
Guaranteed minimumFirst allot guarantee, balance normal ratio.Saves writing two steps.

Quick Revision

PointDetail
1Profit ∝ (Capital × Time) when time differs.
2Convert everything to “capital-months” or “capital-days”.
3Ratio must always be brought to lowest terms (÷ HCF).
4Working partner’s salary % is always on total profit, not on balance.
5Loss sharing uses same ratio as profit unless deed says otherwise.
6Mid-year withdrawal → split timeline & add weighted blocks.
7Guaranteed profit → deduct first, then share remainder.
8Interest on capital is deducted from profit before sharing.
9Difference-type: 1 unit = given difference ÷ (ratio diff).
10In 2-person sums, total parts = sum of ratio numbers; multiply fraction directly.
