Question

The price of a chair is RS 150. If you buy 5 chairs , you will get 10% discount . How much will you have to pay if you buy 10 chairs?

Answer 1

Dear student,


$$\begin{gathered} Priceof1chair=Rs150 \\ Priceof5chair=Rs150\times 5=Rs750 \\ Discount=10\% \\ SPof5chair=750-10\%of750 \\ =Rs\left(750-\frac{10}{100}\times 750\right) \\ =Rs\left(750-75\right) \\ \Rightarrow SPof5chairs=Rs675 \\ \Rightarrow SPof(5\times 2=10)chairs=675\times 2=Rs1350 \end{gathered}$$
