Answer 2

The cost price of the school books​ was Rs. 3550.

Step-by-step explanation:

Required formula:

C.P. = $\frac{100}{100+P} * S.P.$

Let the cost price of the school books be Rs. "x".

The amount customer paid for the books i.e., the selling price of the school books = Rs. 4544

Now, it is given that the owner charges 28% more than the cost price of the school books i.e., we can consider that he will is making gain of 28%.

Thus, putting the values in the above formula, we get

The cost price of the school books as,
