3. A man buys a certain number of articles at 15
for 112.50 and sells them at 12 for 108.
Find :
() his gain as percent;
(ii) the number of articles sold to make a
profit of 75.​

Answer 1

Answer:

gain= cp+sp= 12+15= 72

profit= cp/100+p=

12/100+7 =

Answer 2

CP per article = 112.50/15 = Rs7.50 per article

SP per article = 108/12 = Rs 9 per article

Gain = 9-7.5 = Rs 1.5/ article

Gain% = (1.5/7.5)*100 = 20%

Total profit = Rs75

Profit per article = Rs 1.5

No of articles sold = 75/1.5 = 50 articles
