Question

a sells an article to b at a profit of 20 % . B sells it to C at a loss of 4 % . what does it cost A if C has paid 144 rupee

Answer 1

SP for A = 20%of X
= 20x/100
= 120x/100
SP for A= CP for B
then, CP for B = 120x/100
SP for B = 4%of 100
= 4x/100
= X-4x/100
= 96x/100
CP for C = 144
difference between 120x/100 and 96x-100
= 24 X/100
24x/100=144
24x = 14400
X= 600
and now you put 600 on every value of X
