A farmer sells eggs in trays each contain 30 eggs a shopkeeper sells these in dozens if the shopkeeper needs 91 dozens eggs in a week how many trays of eggs should he buy from the farmer
Grade 11
91*12/30 = 36.4
so, he'll need 37 trays
To figure out how many trays of eggs the shopkeeper should buy from the farmer, we need to convert the number of dozens needed into trays.
Step 1: Find the total number of eggs needed in dozens.
The shopkeeper needs 91 dozens of eggs, and each dozen contains 12 eggs. Multiply these two numbers to get the total number of eggs needed:
91 dozens * 12 eggs/dozen = 1092 eggs
Step 2: Convert the total number of eggs into trays.
Each tray contains 30 eggs. Divide the total number of eggs needed by the number of eggs per tray:
1092 eggs / 30 eggs/tray = 36.4 trays
Since we cannot have a fraction of a tray, we need to round up to the nearest whole number.
Step 3: Round up to the nearest whole number.
36.4 trays rounded up to the nearest whole number is 37 trays.
Therefore, the shopkeeper should buy 37 trays of eggs from the farmer.
12 × 8 = 96
96 ÷ 30 = 3.2
