A sold and article to B at a profit of 20%. B sold the same article to C at a loss of 25% and C sold the same article to D at a profit of 40%. If D paid Rs.252 for the article, then find how did A pay for it?
(A) Rs.110
(B) Rs.200
(C) Rs.240
(D) Rs.300
Solution: Let A’s cost be x.
A → B at 20% profit: B’s price = 1.2x
B → C at 25% loss: C’s price = 1.2x × 0.75 = 0.9x
C → D at 40% profit: D’s price = 0.9x × 1.4 = 1.26x
