Show answer & explanation
Correct answer: D
Step 1: Find the daily rice consumption per person.
Total rice = 200 kg, persons = 40, days = 30.
Rice per person per day = 200 / (40 × 30) = 200 / 1200 = 1/6 kg.
Step 2: Calculate total daily consumption for 30 persons.
Daily consumption = 30 × (1/6) = 5 kg/day.
Step 3: Find number of days to consume 500 kg.
Days = 500 / 5 = 100 days.
हिन्दी उत्तर:
चरण 1: प्रति व्यक्ति प्रति दिन चावल की खपत ज्ञात करें।
कुल चावल = 200 किग्रा, व्यक्ति = 40, दिन = 30।
प्रति व्यक्ति प्रति दिन चावल = 200 / (40 × 30) = 200 / 1200 = 1/6 किग्रा।
चरण 2: 30 व्यक्तियों के लिए कुल दैनिक खपत ज्ञात करें।
दैनिक खपत = 30 × (1/6) = 5 किग्रा/दिन।
चरण 3: 500 किग्रा खाने में कितने दिन लगेंगे?
दिन = 500 / 5 = 100 दिन।
