Question

2. There is 10% profit by selling a book. If the selling price would have been 7 less,
there would have been 4% loss. What is the cost price of the book?
(1) 70 (2) 60 (350 (4) 340​

Answer 1

Step-by-step explanation:

Then selling price(SP1) would be Rs 125

New cost price @20% less = Rs 80

New selling price @30% profit = 130% of 80 = Rs 104

Now, difference between the 2 selling prices = 125–104 = Rs 21.

When difference is 21 then CP = Rs 100

When difference is 1050 then CP = 100*1050/21 = Rs 5000

Hence the cost price of the article is Rs 5000
