Sonia purchased a car for ₹ 450000. She used it for three months and then sold it for ₹ 435000. Find her loss percent?

Given that

CP of car = Rs 450000

SP of car = Rs 435000

Loss % = ?

$$\begin{gathered} loss \% = \frac{CP - SP}{CP} \times 100 \\ loss \% = \frac{450000 - 435000}{450000} \times 100 \\ loss \% = \frac{15000}{450000} \times 100 \\ loss \% = \frac{150}{45} \\ loss \% = \frac{10}{3} = 33.33\% \end{gathered}$$

hence loss % is 33.33 %.
