In a business a man got a profit of Rs. 300.
If he got a profit of 5% what is his invest-
ment?
De 150 ?​

Answer 1

Step-by-step explanation:

Before we start, it’s important to note here that it is not 15% to be added to 5% to make it a total of 20%.

Let the other profit percent be x.

Then, our equation looks like this.

105/100 * 2500 + [(100+x)/100] * 2500 = 120/100 * 5000 → x= 35.

Hence, if he makes a profit of 35% on the second, it comes to a total of 20% profit on the whole.
