Question 146

By selling some goods at ₹31, a salesman loses 7% on his output. Find the percentage profit or loss. When he sells the same at ₹35.

Solution

Selling price = Rs. 31 and loss % = 7%

=> Cost price = $$\frac{31}{(100-7)}\times100$$

= $$\frac{3100}{93}=Rs.$$ $$\frac{100}{3}$$

If selling price = Rs. 35

=> Profit % = $$\frac{35-\frac{100}{3}}{\frac{100}{3}}\times100$$

= $$\frac{(105-100)}{100}\times100=5\%$$

=> Ans - (A)
