Final answer:
To make a profit of 18%, Wamiq should sell the remaining oranges at a price of Rs9.78 per dozen.
Step-by-step explanation:
To calculate the price per dozen at which Wamiq should sell the remaining oranges to make a profit of 18%, we need to first determine the cost price of one orange. If Wamiq purchased one orange for Rs450, the cost price of one orange is Rs450.
Since four dozen oranges were rotten and could not be sold, we subtract four dozen (48) from the total number of oranges purchased, which leaves us with 600 - 48 = 552 oranges.
To find the selling price per dozen, we divide the cost price of one orange by the remaining oranges:
Rs450 ÷ 552 = Rs0.8152 per orange.
There are 12 oranges in a dozen, so the selling price per dozen should be:
Rs0.8152 × 12 = Rs9.78.
Therefore, Wamiq should sell the remaining oranges at a price of Rs9.78 per dozen to make a profit of 18%.
