A sells an article to B at a gain of 10% and B sells it to C at a gain of 5%. If C pays Rs.4,620 for it, what did it cost to A?

Answer»

Rs. 4,000



Let the COST PRICE of A be Rs.100, then the selling price =Rs.110.Now, the cost price of B be Rs.110

 Selling price of B =105/100 × 110 100 231 = Rs. 132/2

∴ C.P. of C = 231/2

But the cost price of C as GIVEN = Rs.4,620

If the cost price of C is Rs. 231/2,

then the C.P. of A = Rs.100

If the cost price of C is Rs.4,620 then the

C.P of A=(100 × 2 × 4620)/ 231

= Rs.4,000
