Question

The cost of a ball is a two digit number. Its selling price has same digits as cost with digits interchanged. If its profit margin is divided by 9, what will be the remainder of division?

Answer 1

Remainder would be 0.

Step-by-step explanation:

Consider the provided information.

The cost price of the article = 10x + y

Its selling price has same digits as cost with digits interchanged.

Thus, the selling price is = 10y + x

Profit = Selling price - Cost price

Profit = ( 10y + x ) - ( 10x + y )

Profit = 10y + x - 10x + y

Profit = 9y - 9x

Profit = 9(y-x)

So, we can say that the profit is multiple of 9,

Hence, when we divide the profit by 9,
