Marks: +1, -0

An article is marked x% above the cost price. A discount of

2/3x%

is given on the marked price. If the profit is 4% of the cost price and the value of x lies between 25 and 50, then die value of 50% of x is :

Solution:

Let C.P. = 100, then M.P.

= 100+x

S.P.=(100+x)-{2x}/300(100+x)=100+4

⇒ x^2 - 50x + 600 = 0

⇒x=20,30

⇒x/2=10,15
