Question

A bookseller sold 400 copies of a book at a profit of 20 percent.If the cost price of a book is rupees 100,find the selling price of the book

Answer 1

(  THIS IS ALL IN TABULAR FORM)
PRICES          IN TERMS OF 100                                          IN TERMS OF DATA
C.P         100 ( C.P IS ALWAYS 100 IN TERMS OF 100)               40,000
S.P                 ∵ IT IS A PROFIT IT IS 120                                                    X

(NOW NOT IN TABULAR FORM)
100X= 120*40,000
100X= 48,00,000
X= 48,00,000/100
X=48,000
∴THE SELLING PRICE= RS. 48,000
I HOPE IT HELPS
