Question
A and B started a business by investing ₹48,000 and ₹72,000 respectively. After 6 months, A withdrew half of his capital, while B increased his capital by ₹24,000. At the end of the year, they earned a total profit of ₹55,000. What is B's share in the profit?
- A. ₹26,500
- B. ₹28,000
- C. ₹38,500 (Correct answer)
- D. ₹36,000
Correct Answer
Option C — ₹38,500
Detailed Solution & Explanation
The correct answer is ₹38,500.
Key Points
- Capital changes mid-year, so compute each partner's capital × time in two halves:
- A: 48,000 × 6 + 24,000 × 6 = 288,000 + 144,000 = 432,000
- B: 72,000 × 6 + 96,000 × 6 = 432,000 + 576,000 = 1,008,000
- Ratio A : B = 432 : 1,008 = 3 : 7, totalling 10 parts.
- B's share = 7/10 × 55,000 = ₹38,500.
Additional Information
- "Withdrew half his capital" leaves 24,000, and "increased by ₹24,000" makes B's second-half capital 96,000 — read both phrasings carefully, as one is a proportion and the other an absolute amount.
- The general rule for any number of capital changes is to break the year into intervals of constant capital, compute capital × months for each, and sum.
- A quick sanity check: B invested more and then added further, so B's share must exceed half the profit — which immediately rules out ₹26,500.
