When A commodity is sold for Rs. 34.80, there is a loss of 25%. What is the cost price of the commodity?
Solution
Correct Answer: Option A
\(Loss\;\% \; = \;\frac{{loss}}{{cost\;price}}\; \times \;100\%\)
Given, loss % = 25 %
\(\Rightarrow 25\% = \frac{{loss}}{{cost\;price}}\; \times \;100\%\)
⇒ 0.25 × cost price = loss
Selling price = cost price – loss
Given, selling price = 34.80
⇒ 34.80 = cost price – 0.25 × cost price
⇒ 34.80 = 0.75 × cost price
⇒ Cost price = 34.80/0.75
⇒ Cost price = 46.40
