A fruits seller bought some lemon for Re 1 for 15 lemon. if he sold all lemons at 25% profit, how many lemons were sold for Rs 1.​

Answer 1

12 lemons

Explanation:

CP of 15 lemon = ₹ 1

Profit = 25 %

SP of 15 lemons =
`(100+profit)/(100)*CP`

`= (125)/(100)*1\\\\= (5)/(4)`

SP of 15 lemons = ₹
`(5)/(4)`

Number of lemon for ₹
`(5)/(4)` = 15

Number of lemons for ₹ 1 = 15 ÷
`(5)/(4)`

`= 15 *(4)/(5)\\\\= 3*4\\\\= 12`
