Question

Q. there were 200 fishes in an aquarium, 99% of which were red. how many red fishes must be removed to make the percentage of red fishes 98%?

Answer 1

2 fishes must be removed

99% × 200 (total fishes ) = no. of red fishes = 198
98% × 200 (total fishes ) = no. of red fishes = 196


So, to get 98% red fishes we need to remove 2 red fishes (198 - 196)
