SSC CGL 20161)When an article is sold for Rs.355, there is a loss of 29%. To gain 21%, it should be sold for Rs. :
605
Selling price = 355;
Loss = 29%;
Cost price =\( \frac{355}{100 - 29} \times 100 = \frac{355}{71} \times 100 \)= Rs.500;
For 21% gain,
Selling price = \(500 \times \frac{121}{100}\) = Rs.605
SSC CGL 20162)An article is sold at a certain price. If it is sold at \(33\frac{1}{3}\%\) of this price, there is a loss of \( 33\frac{1}{3}\%\) What is the percentage profit when it is sold at 60% of the original selling price?
20
Let the selling price of an article be Rs.100.
Now,
Selling price = \(100 \times 1/3 \) = 33.33;
Loss = \(33\frac{1}{3}\)\%;
(100 - 33.33)% of the cost price = 33.33;
66.67% of the cost price = 33.33;
Cost price =\( \frac{33.33}{66.67} \times 100\) = 50;
60% of the original selling price = 60;
Profit = 60 - 50 = 10;
Profit percentage =\( \frac{10}{50} \times 100 \)= 20%
SSC CGL 20163)A person buys 80 kg of rice and sells it at a profit of as much money as he paid for 30 kg. His profit percent is:
\(37\frac{1}{2}\)%
Let the man has purchased the Rice at price of Re.1/ Kg;
Cost Price of 80 Kg = Rs 80;
Profit = Rs30;
Profit % = \({30 \over 80}\times100 = 37.5\);
SSC CGL 20164)If a shop keeper marks his goods for a certain amount so as to get 25% gain after allowing a discount of 20%, then his marked price is
