Question

A green grocer had a profit of Rs.47 on Monday, a loss of Rs.12 on Tuesday and loss of Rs.8 on Wednesday. Find his net profit or loss in 3 days.

Answer 1

Hint:
We will consider the profit as add-on i.e., a positive integer and the loss to be a negative integer (one explanation can be that profit adds up and gives us benefits and loss reduces the amount by a certain amount). We will add all the values with their signs (as – or +). The sign of the net value will show if the net value results in profit or loss.

Complete step by step solution:
We are given that a green grocer had profit / loss on specific week days.
On Monday, he had a profit of Rs.47.
On Tuesday, he faced a loss of Rs.12.
On Wednesday as well, he had a loss of Rs.8.
We are required to calculate the net value (profit / loss) in these 3 days.
Let us assume that the profit is a positive integer as it adds up into the net value and let the loss be considered as a negative integer since it deducts a specific amount of value from the net total.
Therefore, the net profit / loss = profit on Monday + loss of Tuesday + loss on Wednesday
$ \Rightarrow $ net profit / loss = 47 + (-12) + (-8) = 47 – 12 – 8 = 27
$ \Rightarrow $ net total = + 27 = profit.

Here, the net total comes out to be a positive value, therefore, he gains a net profit of Rs.27 in three days.

Note:
One variation of this question can be instead of 3 days profit or loss they might have asked the same for 7 days or a month with a pattern something like grocer having profit on even date of 20 rs. and loss of 15 Rs. on odd days. In such a case we need to find net profit or loss and then it’s percentage.
