Question

If cp of 4 book is the same as the sp of 3 books find its profit or loss

Answer 1

Let cp of 4 book = sp of 3 book = x

cp of 1 book =x/4

sp of 1 book=x/3

here sp is more

so, gain= sp -cp

=x/3 - x/4

= (4x-3x)/12

= x/12

gain percent = (x/12/x/4) *100

= 100/3 percent

=33.333 percent

Answer 2

Answer:

33 1/3 % Profit

Please mark the brainliest hope it helps

Step-by-step explanation:

cp of 4 books= sp of 3 books

cp of 1 book=1/4x

sp of 1 book=1/3x

1/4x=1/3x

1/3 > 1/4

SP > CP= Profit

Profit= SP - CP

x/3 - x/4= 4x/12- 3x/12= x/12

Profit % = Profit/CP X 100

(x/12 ÷ x/4) X 100= (x/12 X 4/x) X 100= 1/3 X 100= 33 1/3%
