alleryएक वस्तु 20% की हानि पर 15,000 में बेची जाती है। इसका क्रय मूल्य क्या था?
A12,000
B17,250
C18,750
D18,000
Answer & Solution
Correct answer: C. 18,750
1. 20 प्रतिशत की हानि का अर्थ है कि विक्रय मूल्य क्रय मूल्य का 80 प्रतिशत है।
2. अतः क्रय मूल्य का 80 प्रतिशत = 15000.
3. एक प्रतिशत = 15000 / 80 = 187.5 होगा।
4. क्रय मूल्य = 100 x 187.5 = 18750 है।
5. 15000 में 20 प्रतिशत जोड़ने पर 18000 प्राप्त होता है, जो गलत है क्योंकि हानि की गणना क्रय मूल्य पर की गई थी, न कि विक्रय मूल्य पर।
