Question

By selling an article for Rs. 72, there is a loss of 10%. In order to gain 5%, its selling price should be (a) Rs. 87 (b) Rs. 85 (c) Rs. 80 (d) Rs. 84

Answer 1

Answer:

d

Step-by-step explanation:

Let CP=x

SP=[(100-Loss%)/100]×CP

72=[(100-10)/100]×CP

=90/100×CP

CP=72÷90/100=72×100/90=72×10/9=80

SP=[(100+Profit%)/100]×CP

=[(100+5%)/100]×80

=105/100×80=84
