Answer: B
Solution: Assume the cost price of one item is 100. At 25% profit, its selling price is 125. The cost price of 20 items is 2000, so \(125x=2000\Rightarrow x=16\). Trick: \(x=\frac{20\times100}{125}=16\).
दिया गया है कि 20 वस्तुओं का क्रय मूल्य, x वस्तुओं के विक्रय मूल्य के बराबर है और लाभ प्रतिशत 25% है। x का मान ज्ञात कीजिए।

उत्तर: B
हल: एक वस्तु का क्रय मूल्य 100 मानें। 25% लाभ पर उसका विक्रय मूल्य 125 होगा। 20 वस्तुओं का क्रय मूल्य 2000 है, इसलिए \(125x=2000\Rightarrow x=16\)। ट्रिक: \(x=\frac{20\times100}{125}=16\)।
