If an article is sold at a gain of 5 % instead of being sold at a loss of 5 %, a man gets Rs. 5 more. What is the cost price of the article ?
(a) Rs. 50
(b) Rs. 40
(c) Rs. 60
(d) Rs. 80
Answer : (a)
In first case, gain = 5 %
and in second case, loss = 5 %
and difference = Rs. 5 more
But difference in % = 5 + 5 = 10 %
CP = 10010×5=Rs.50
