A shopkeeper has some eggs. He wants to put them in trays which can have exactly 12 eggs. He filled 9 trays with eggs and left with 5 eggs. How many more number of eggs does he need so that no egg is left out after completing the 10th tray? Correct Answer 7

Given:

Total eggs can have in a tray = 12

Total trays filled = 9

Total eggs left = 5

Calculation:

According to the question, a tray can have a maximum of 12 eggs.

After filling 9 trays, 5 eggs remain to be filled in the 10th tray.

The required eggs for 10th tray to be filled = (12 - 5) = 7

∴ He needs a total of 7 more eggs so that no egg will be left after completing the 10th tray.
