From the question, it’s given that,

Number of pastries = 15 Number of biscuit packets = 12

So, the required number of boxes that will contain an equal number of both pastries and biscuits will be the HCF of 15 and 12.

So, applying Euclid’s division lemma, we have

15 = 12 x 1 + 3

12 = 3 x 4 = 0

So, the number of boxes required = 3

∴ Each box will contain 15/3 = 5 pastries and 12/3 = 4 biscuit packs.
