There were 200 fish in an aquarium

Solve This !!!!!!


There were 200 fish in an aquarium, 99% of which were red. How many red fish must be removed to make the percentage of red fish 98%?


Answer

99% of Red Fishes would be – 200 X 0.99 = 198
Removing “x” of fishes & 98 % red fishes in the aquarium
198-x = 0.98 (200-x)
198-x = 198-.98x
0.2x = 2
X= 100
