Answers
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.
