By selling an article for Rs. 720, a man loses 10%. At what price should he sell it to gain 5%?
Correct
Answer : a
SP = Rs. 720 and loss = 10%
∴CP = (100/90) *720 = Rs. 800

Question 4 of 5
4. Question
Rajdeep loses 20% by selling a radio for Rs. What per cent will he gain by selling it for Rs. 1020?
Correct
Answer : c
SP = Rs. 768 and loss = 20%
∴CP = (100/80)*768 = (5/4 )*768 = Rs. 960
Now, CP = Rs. 960 and SP = Rs. 1020
Gain = 1020 – 960 = Rs. 60
∴Gain % = (60/960)*100%= 6.25%
Incorrect
Answer : c
SP = Rs. 768 and loss = 20%
∴CP = (100/80)*768 = (5/4 )*768 = Rs. 960
Now, CP = Rs. 960 and SP = Rs. 1020
