Correct answer: D. Rs. 4040 रुपये
Explanation
Let the cost price be C. Selling at a 20% loss gives 0.8C and at a 10% gain gives 1.1C, and the difference is Rs. 12. So 1.1C − 0.8C = 0.3C = 12, which gives C = Rs. 40.माना क्रय मूल्य C है। 20% हानि पर विक्रय मूल्य 0.8C तथा 10% लाभ पर 1.1C होगा, और इनका अन्तर 12 रुपये है। अतः 1.1C − 0.8C = 0.3C = 12, जिससे C = 40 रुपये प्राप्त होता है।More Mathematics & Numerical Ability questions
