Question

d) A shopkeeper sold a music system for Rs. 12,500 at a profit of 25%. Find
the cost price of the music system.​

Answer 1

Answer:

I'm not aware of the formulas you use to solve this question, but will still try...

Let the Cost Price be 'x'.

We know that:

Selling Price = Cost Price + Profit %

$12500 = x + ( \frac{25}{100} \times x) \\ 12500 = x + \frac{1}{4} x \\ 12500 = \frac{5}{4} x \\ 50000 = 5x \\ 10000 = x$

Thus, the selling price of the music system is Rs. 10000

Thanks.
