Question

Out of 200 fish in an aquarium 99%are red how many red mustbe removed in ordee to reduce the percentage of red fish to 98%

Answer 1

Answer:

This is very easy question you have just to make equation than it will be solved easily. Number of red fish = 99% of 200 = 198. Let the number of red fish removed be x. 198 - x = 98% of 200 - x

⇒198−x=98/100∗200−x

⇒19800−100x=19600−98x

⇒19800−19600=100x−98x

⇒200=2x⇒x=100

So, we have to remove 100 red fish so the number of red fish in total become 98%. It is quit unbelievable answer, the difference of percentage is 1 but the difference in number is 100.
