15 pastries and 12 biscuit packets have been donated for a school fete.

We are given that 15 pastries and 12 biscuit packets have been donated for a school fete. These are to be packed in several smaller identical boxes with the same number of pastries and biscuit packets in each. We need to find the number of biscuit packets and number of pastries each box contain.

Given that

Number of pastries = 15

Number of biscuits packets = 12.

Therefore, required number of boxes to contain equal number = H.C.F. of 15 and 12.

By applying Euclid’s division lemma

$15=12 \times 1+3$

$12=3 \times 4+0$

Therefore, number of boxes required $=3$.

Hence each box will contain 5 pastries and 4 biscuits pac
