A Zoo has 66 fishes , some white and rest orange , Which of the follow...
Solution:

Let the number of white fishes be x and the number of orange fishes be y.

Given, x + y = 66 (Total number of fishes)

We are supposed to find the ratio of white to orange fishes.

Therefore, the required ratio = x : y

We can write x : y as (x/y) : 1

Now, we need to check which option gives us a value of x/y.

a) 1:7 => x/y = 1/7 = 0.14
b) 2:9 => x/y = 2/9 = 0.22
c) 3:7 => x/y = 3/7 ≈ 0.43
d) 2:5 => x/y = 2/5 = 0.4

From the given options, only option (b) gives us a value of x/y.

Therefore, the required ratio of white to orange fishes in the zoo is 2:9.
