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.
