Correct answer: (A) Rs 60
Total cost = (20 x 38) + (20 x 62) = 760 + 1240 = 2000. Total quantity = 20 + 20 = 40. Mean cost price per kg = 2000 / 40 = Rs 50. To gain 20% profit, selling price per kg = 50 x (1 + 20/100) = 50 x 1.2 = Rs 60.

सही उत्तर: (A) Rs 60
कुल लागत = (20 x 38) + (20 x 62) = 760 + 1240 = 2000। कुल मात्रा = 20 + 20 = 40। औसत लागत मूल्य प्रति किग्रा = 2000 / 40 = 50 रुपये। 20% लाभ पाने के लिए, विक्रय मूल्य प्रति किग्रा = 50 x (1 + 20/100) = 50 x 1.2 = 60 रुपये।
