Profit per cent 4. A dishonest dealer defrauds to the extent of x % in buying as well as selling his goods by using faulty weight. What will be the gain per cent on his outlay?
a) 10/x x2 % b) 2x% c) x x2/100 % d) None of these
Ans: d
Solution: Let the CP of each article be Re 1
Percentage of dishonesty = 10% (Here x% = 10%)
Actual CP = 100/110 = Rs 10/11
Since He buys 110 articles in Rs 100
Since He sells 90 articles at the CP of 100 articles
Actual SP = 100/90 = 10/9
Profit per cent
(10/9 – 10/11) / 10/11 × 100
20/99 × 11/10 × 100 = 200 / 9
= 22 2/9% 5. If 10% loss is made on selling price, then the percentage of loss on the cost price will be?
a) 9 1/11% b) 11 1/9% c) 15% d) 21%

Solution: According to the question,
Loss% = CP – SP / SP
Where CP = Rs x
SP = Rs y
=>; 10/100 = x – y / y = 1/10
=>; 10x – 10y = y
