Question

A man purchases two clocks A and B at a total cost of Rs. 650. He sells A with 20% profit and B at a loss of 25% and gets the same selling price for both the clocks. What are the purchasing prices of A and B respectively?

Answer 1

Answer:

Let X and Y be the purchase price of clock A and B

Therefore

X + Y = 650

Now,

1.2X = 0.75Y

X = 7.5/12 Y

Putting in the above equation

7.5/12 Y+ Y= 650

Y = (650×12)/19.5

Y = 7800/19.5

Y = 78000/195

Y = 400 and  X = 250

Therefore, purchasing price of A is Rs. 250 and B is Rs. 400.
