Question

There is decrease in sale of object by 10% due to increase in the cost of object by 10%, then what is the profit present or loss persent in this transaction ?​

Answer 1

There is a loss of 1 % in this transaction.

Step-by-step explanation:

Let x% decrease in sale and y% increase in cost then total profit and loss,

$(-x + y - \frac{xy}{100})$

Here x = 10 %

y = 10 %

Plug these values in given formula,

$(-10 + 10 - \frac{10\times 10}{100})$

= - 1 % [negative sign for loss]

Hence, there is a loss of 1 % in this transaction.
