Question

If the box contains identical books, find the weight of each book.

• A. 15 g
• B. 1,500 g
• C. 0.15 g
• D. 150 g

Answer 1

The correct option is D 150 g

Total weight of box = 750 g
Number of identical books present = 5

So, we see:

Solving by long division method, we observe:

$$\begin{array}{c}150\\ 5750\\ -\underset{–}{5}2\\ 25\\ -\underset{–}{25}\\ 00\\ -\underset{–}{00}\\ 0\end{array}$$

So, weight of each book = 150 g
