Question

A carton holds 41 packets of biscuits, each having 13 biscuits. How many biscuits can be packed in the carton?

Answer 1

Number of biscuits in one packet = 13
Number of packets in one carton = 41
Total number of biscuits in one carton = 41 x 13
$\begin{array}{ccccc}& & 4& 1& \\ & \times & 1& 3& \\ & 1& 2& 3& (41\times 3)\\ +& 4& 1& & (41\times 1)\\ & 5& 3& 3& \end{array}$
Hence, a total of 533 biscuits can be packed in the carton.
