Question

A fruit seller first sells 16 mangoes for Rs 2 then 30 mangoes for Rs 3 and lastly 84 mangoes for Rs 5 . What is the average number of mangoes per rupee he sells?​

Answer 1

Answer:

Let, cost price = Rs 100x/kg

According to the question,

⇒ 100x - 100x × 10/100 = 9

⇒ 90x = 9

⇒ x = 0.1

∴ Cost price of mangoes = Rs 100 × 0.1 = Rs 10/kg

∴ Selling price at 5% profit = Rs (10 + 10 × 5/100) = Rs 10.5/kg  solve like this
