Question

A manufacturer marks his goods in advance at 80 percent more than the cost price, but he
allows 15 articles to the dozen and also 10 percent discount for cash. What rate of profit
on his outlay does he obtain from a customer who pays cash?​

Answer 1

Answer:

product to be Rs. 100/-

Market price = 130% of 100 = 130

Selling price = 130 -15% of 130 = 110.5

So net Profit = 110.5 - 100 = 10.5 Rs on Rs 100

So net percentage gain = 10.5%

Answer 2

Answer:

29.6 Percent

Step-by-step explanation:

Formula to Know

1) Discount Percent  = No of Freebies/Total Number of Articles

2) Successive percentage Formula = A% + B% + (A*B/100)%

Now,

He marks the goods 80 percent above CP

=> MP=1.8CP

Gives 15 articles to a dozen => Discount 1 = (3/15)*100= 20% (Look at formula 1)

Discount 2 = 10%

Total Discount = (-20) + (-10) + (-20*-10)/100 = -28% or -0.28

=> SP = (1-0.28)MP =0.72MP=0.72*1.8CP

Profit = (0.72*1.8-1)*100 = 29.6%
