Read this question in English
A sum of ₹ 2,500 is distributed among X, Y and Z in the ratio 1/2: 3/4: 5/6. What is the difference between the maximum share and the minimum share?
(a) ₹ 300 · (b) ₹ 350 · (c) ₹ 400 · (d) ₹ 450
उत्तर और व्याख्या · explanation in English
Answer: (c) ₹ 400
Clearing the fractions by multiplying by 12 turns the ratio into 6 : 9 : 10, a total of 25 parts worth ₹ 100 each. The largest share (10 parts) exceeds the smallest (6 parts) by 4 parts, or ₹ 400.
- Multiply 1/2 : 3/4 : 5/6 by 12 to get 6 : 9 : 10.
- Total parts = 25; one part = 2,500 ÷ 25 = ₹ 100.
- Maximum − minimum = (10 − 6) × 100 = ₹ 400.
- Check: shares 600 + 900 + 1,000 = 2,500.
Remember · For a ratio of fractions, multiply every term by the LCM of the denominators to get whole-number parts.
