Question

A shopkeeper had a profit of ₹$50$ on Monday, a loss of ₹$20$ on Tuesday and a loss of ₹$18$ on Wednesday. Find his net profit or loss in these three days.

Answer 1

GIVEN- Profit of ₹$50$ on Monday, a loss of ₹$20$ on Tuesday and a loss of ₹$18$ on Wednesday.

Let us denote the profit by positive integer and loss by negative integer.

Therefore, the numbers can be written as $+50,-20,-18.$

$=$$+50+(-20)+(-18)$.

$=50-20-18.$

$=12.$

Hence, the net profit is $=12$.
