Question

THE printed price of a book is 400 the discount given is 10%.the profit is 12% then cp

Answer 1

Solution:-
Printed price of the book = Rs. 400
Discount given = 10 %
Discount in rupees = 40 Rs.
Then Selling price = 400 - 40 = Rs.360
Profit earned = 12 %
So, Cost price = (100 × 360)/(100 + 12)
⇒ 36000/112
Cost price = Rs. 321.42
Answer.

Answer 2

Printed price = 400
Discount = 10 % of printed price
               = 400 * 10/100 = 40
So sale price = 400 - 40 = 360

Cost price + profit = sale price
So cost price * (100+12)/100 = 360

cost price = 360 *100/112 = 2250/7 = 321.42
