Question

A bookseller sends $78$ bundles of books through a transport carrier. Each bundle contains $387$ books and each book weighs $2$Kg. Find the total weights of books to be transported.

Answer 1

Given: Total number of bundles $=78$

Number of books in each bundle $=387$

Weight of each books $=2$Kg

Total weights of books to be transported $=$Total number of bundles $\times$Number of books in each bundle $\times$Weight of each books

$=78\times 387\times 2$

$=156\times 387$ $\left(\because 78\times 2=156\right)$

$$\begin{gathered} 156 \\ \times 387 \\ \_\_\_\_\_\_\_\_\_\_ \\ 1092 \\ +12480 \\ 46800 \\ \_\_\_\_\_\_\_\_\_\_ \\ 60372 \end{gathered}$$

Hence, the total weight of books to be transported is $60372$Kg.
