Question

by selling a book for rs 8400, a dealer suffered a loss of 4%. At what price should it be sold to gain 8%

Answer 1

Answer:

Step-by-step explanation:

let original price be x

In losing 4%

s.p = x - ( 4/100 × x )

24480 = x - x/25

24480 = 24/25 × x

x = 25500

To gain 4%

s.p = x + (4/100 × x)

= 25500 + 1020

= 26520

Answer 2

Answer:

Step-by-step explanation:

loss=8400*4/100=336

4%  =336 rupees

8% gain=4%+4%

so selling price to gain 8%=book price+8%(4%+4%)

                                            =8400+336+336

                                             =9072 rupees
