alleryएक अलमारी 5% की छूट के बाद 5,225 में बेची जाती है। इसका अंकित मूल्य क्या था?
A5,450
B5,500
C5,600
D5,750
Answer & Solution
Correct answer: B. 5,500
1. 5 प्रतिशत छूट का अर्थ है कि खरीदार अंकित मूल्य का 95 प्रतिशत भुगतान करता है।
2. अतः अंकित मूल्य का 95 प्रतिशत = 5225.
3. इसलिए एक प्रतिशत = 5225 / 95 = 55 होगा।
4. कुल अंकित मूल्य = 100 x 55 = 5500 है।
5. 5225 में 5 प्रतिशत जोड़ने पर 5486 प्राप्त होगा, इसीलिए विक्रय मूल्य से उल्टी गणना करते समय 105 के बजाय 95 का उपयोग किया जाना चाहिए।
