Question

A shopkeeper makes a profit of Rs. 46 in a day by selling gel pens. He notices that the profit made by him is 5 less than thrice the number of gel pens sold by him. If he sells '$p$' number of gel pens in a day then the correct equation for profit is

• A. p + 5 = 46
• B. 3p + 5 = 46
• C. p - 5 = 46
• D. 3p - 5 = 46

Answer 1

The correct option is D

3p - 5 = 46

Given, the shopkeeper makes a profit of Rs. 46 in a day by selling gel pens.
Also, the profit made by him is 5 less than thrice the number of gel pens sold by him.
Let the number of gel pens sold be $p$.
Then 5 less than thrice the number of gel pens sold = $3p-5$
And this is equal to 46.
Hence, equating both, we get the equation as
$3p-5=46.$
