Question

Loss Is Denoted by a negative integer and profit is denoted by a positive integer. A shop keeper earns a profit of Rs. 8 /- per toy car and a loss of Rs. 5 /- per toy lorry. If he sells 300 toy cars and 500 toy lorries, What is his profit OR loss?​

Answer 1

It is his loss of 100 Rupees.

We consider the profit as positive and loss as negative.

1. Profit earned is Rs. 8 per toy and loss is Rs.5 per lorry.
2. Total earned will be the sum of profit multiplied by the number of toys sold and loss multiplied by the number of lorries sold.
3. Total money earned is (+8 * 300) + (-5 * 500) = 2400 - 2500 = -100
4. Net income is negative that denotes loss.
