Correct answer: (C) 3
Selling at 5 lemons per rupee gives SP=Rs 0.20 per lemon, which represents a 34% loss, so CP = 0.20/0.66 = Rs 0.303 per lemon. To gain 10%, SP must be 0.303*1.10 = Rs 0.333, meaning he must sell 1/0.333 = 3 lemons per rupee.

सही उत्तर: (C) 2
5 नींबू प्रति रुपये में बेचने पर SP=0.20 रुपये प्रति नींबू मिलता है, जो 34% हानि दर्शाता है, इसलिए CP = 0.20/0.66 = 0.303 रुपये प्रति नींबू है। 10% लाभ के लिए, SP = 0.303*1.10 = 0.333 रुपये होना चाहिए, अर्थात उसे 1/0.333 = 3 नींबू प्रति रुपये बेचने होंगे।
