Question 137

By selling an article for ₹450. I lose 20%. For what amount should I sell il to gain 20% ?

Solution

Selling price = Rs. 450 and loss % = 20%

=> Cost price = $$\frac{450}{(100-20)}\times100$$

= $$450\times\frac{5}{4}=Rs.$$ $$562.50$$

$$\therefore$$ Selling price to gain 20% = $$\frac{(100+20)}{100}\times562.50$$

= $$\frac{6}{5}\times562.50=Rs.$$ $$675$$

=> Ans - (D)
