Question

A man ordered all the 3 items given in the list and got a discount of $20\%$ on the item with the lowest value. Find the percentage discount on the total amount.
$\begin{array}{cc}\text{Item}& \text{price (in}\$)\\ \text{Book}& 12\\ \text{Pen}& 8\\ \text{Pencil}& 5\end{array}$

• A. $2\%$
• B. $4\%$
• C. $5\%$
• D. $3\%$

Answer 1

The correct option is B $4\%$

From the table given, the price of a book is $\$12$, a pen is $\$8$, and a pencil is $\$5$.
Given that the discount of $20\%$ is given on the pencil.
So, the total discount $=20\%$ of $\$5=\frac{20}{100}\times 5=\$1$
Now, the total price of all the items $=\$12+\$8+\$5=\$25$.
So, the percentage discount on the total amount $=\frac{1}{25}\times 100=4\%$.
