To determine Mr. Zakir's ratio of profit earning, we can follow these steps:
-
Calculate the Cost Price (CP):
- Mr. Zakir bought 3 dozen eggs.
- 1 dozen = 12 eggs, so 3 dozen = 36 eggs.
- The total cost for 36 eggs = Rs. 105.
-
Calculate the Number of Eggs Sold:
- During transit, 4 eggs were broken, so the number of eggs that were unbroken = 36 - 4 = 32 eggs.
-
Calculate the Selling Price (SP):
- Mr. Zakir sells each egg for Rs. 4.
- Therefore, the total selling price for 32 eggs = 32 eggs × Rs. 4/egg = Rs. 128.
-
Calculate the Profit:
- Profit = Selling Price - Cost Price
- Profit = Rs. 128 - Rs. 105 = Rs. 23.
-
Calculate the Ratio of Profit:
- Profit Ratio = Profit / Cost Price = Rs. 23 / Rs. 105.
- To express this as a ratio, we simplify:
- The ratio of profit to cost can be expressed as 23:105.
- We can also convert this to a percentage:
- Percentage of profit = (Profit / Cost Price) × 100 = (23 / 105) × 100 ≈ 21.90%.
Thus, the ratio of Mr. Zakir's profit earning is 23:105.
