Question
A sells an article to B at a profit of 20% and B sells
it to C at a profit of 20%. If C pays ₹504 for it, what was the cost price for A?Solution
Let the CP of A =100. SP of A at the 20% profit =120. SP of A will be CP of B. CP of B =120 Now SP of B at the 20% profit =120×120/100 =144. SP of B will be CP of C. CP of C =144 But ATQ- 144=504 1=504/144=3.5 100 =350.Rs. CP of A =350
