Question

The price list of a stationery shop is given.
$\begin{array}{cc}\text{Object}& \text{price (in}\$)\\ \text{Pen}& 5\\ \text{Pencil}& 3\\ \text{Notebook}& 8\\ \text{Textbook}& 8\\ \text{File}& 10\\ \text{Marker}& 10\\ \text{Whiteboard}& 16\end{array}$
If a boy had the amount of money to buy exactly one item from the list without any remaining balance, what percent of the total amount would be used to buy a pen, a pencil, a notebook, and a textbook?

• A. $50\%$
• B. $30\%$
• C. $40\%$
• D. $60\%$

Answer 1

The correct option is C $40\%$

Given, the total amount of money the boy had = Sum of the value of all the items in the list $=5+3+8+8+10+10+16=\$60$
To buy a pen, a pencil, a notebook, and a textbook, the total amount required to be paid $=5+3+8+8=\$24$
So, the required percentage $=\frac{24}{60}\times 100=40\%$
Therefore, the boy used 40% of the total money that he had to buy the given things.
