The correct option is D 3
We will solve this problem by using repeated subtraction.
Total eggs = 18
Number of eggs in 1st box = 6
Number of eggs left after filling the 1st box = 18 − 6 = 12 Number of eggs left after filling the 2nd box = 12 − 6 = 6
Number of eggs left after filling the 3rd box = 6 − 6 = 0
Thus, total number of boxes required to pack 18 eggs in groups of six is 3.
