Show answer & explanation
Correct answer: D
Step 1: Convert the correct ratio 1/2 : 1/3 : 1/4 to whole numbers. Multiply each term by the LCM of denominators (12):
1/2 × 12 = 6, 1/3 × 12 = 4, 1/4 × 12 = 3 → Correct ratio = 6 : 4 : 3
Step 2: Total parts in correct ratio = 6 + 4 + 3 = 13
Correct shares:
A = (6/13) × 234 = ₹108
B = (4/13) × 234 = ₹72
C = (3/13) × 234 = ₹54
Step 3: Incorrect ratio = 2 : 3 : 4. Total parts = 2 + 3 + 4 = 9
Incorrect shares:
A = (2/9) × 234 = ₹52
B = (3/9) × 234 = ₹78
C = (4/9) × 234 = ₹104
Step 4: Calculate gain for each person:
A: ₹52 - ₹108 = -₹56 (loss)
B: ₹78 - ₹72 = ₹6 (gain)
C: ₹104 - ₹54 = ₹50 (gain)
C gains the most with ₹50.
हिन्दी उत्तर:
चरण 1: सही अनुपात 1/2 : 1/3 : 1/4 को पूर्ण संख्याओं में बदलें। हरों का ल.स. (12) से गुणा करें:
1/2 × 12 = 6, 1/3 × 12 = 4, 1/4 × 12 = 3 → सही अनुपात = 6 : 4 : 3
चरण 2: सही अनुपात में कुल भाग = 6 + 4 + 3 = 13
सही भाग:
A = (6/13) × 234 = ₹108
B = (4/13) × 234 = ₹72
C = (3/13) × 234 = ₹54
चरण 3: गलत अनुपात = 2 : 3 : 4। कुल भाग = 2 + 3 + 4 = 9
गलत भाग:
A = (2/9) × 234 = ₹52
B = (3/9) × 234 = ₹78
C = (4/9) × 234 = ₹104
चरण 4: प्रत्येक व्यक्ति का लाभ गणना करें:
A: ₹52 - ₹108 = -₹56 (नुकसान)
B: ₹78 - ₹72 = ₹6 (लाभ)
C: ₹104 - ₹54 = ₹50 (लाभ)
C को सबसे अधिक ₹50 का लाभ हुआ।
