A vegetable vendor sold 1 kg of potatoes for ₹25 and earned 25% profit. In the evening, he started selling potatoes with only 10% profit. At what cost (in ₹) per kg did he sell the potatoes in the evening ?
Answer & explanation
Correct answer: option 4
CP of one kg potatoes = 25 × \(\frac{100}{125}\) = 20
SP of one kg of potatoes = 20 × \(\frac{110}{100}\) = 22
