​

Answer 1

ANSWERS:--cost price

a) 975.2

b) 999

EXPLANATIONS:--

Given

cost price of the book =920                        

Profit%=6%                                                    

We know,

selling price = (100 + profit%)cost price/100                                                    

                     = (100 + 6%) × 920/100

=(106)× 92/10

=(106×92)/10

=9752/10

=975.2

Therefore, the selling price of the book is 975.2

(b) CP =1080rs and loss =7.5%

Given

cost price of the book 1080                        

loss%=7.5%                                                    

We know,

selling price = (100 + loss%)cost price/100                                                    

                     = (100 -7.5%) × 1080/100

=(92.5)× 1080/100

=(92.5 ×108)/10

=9990/10

=999

Therefore, the selling price of the book is 999.

Formulas for these types of sum

=>cost price or cp=selling price-loss

=>profit =profit percentage/cost price×100

=>selling price=cost price +profit

=>loss=cost price - selling price

Required data,

Cost price=920ruppes

gain percentage=6%

To solve the sum we use the formula of profit and selling price

Cost price=920 ruppes

therefore profit=920×6/100ruppes

=55.2 ruppes

therefore selling price=cost price+ profit

=920+55.2 ruppes

=975.2 ruppes
