You are a bus driver. The bus starts out empty.
At the first stop 4 people get on.
At the second stop, 8 people get on and 3 get off.
At the third stop, 2 people get off and 4 get on.
The question is, what color are the bus driver's eyes?
Since the riddle starts out by saying you are the bus driver, the answer would be the color of your own eyes.

Explanations:
Multiplication of the 1st & 2nd numbers, 5*3 = 15; 9*2 = 18…thusly, 7*2 = 14
Multiplication of the 1st & 3rd numbers, 5*2 = 10; 9*4 = 36…thusly, 7*5 = 35;
Multiplication of the 1st & the sum of the 2nd & 3rd numbers. The generated result is reduced by the value of the 2nd number, …thusly, 7*(2+5) = 49 - 2 = 47
Presume that you do not know what a rhino looks like. Now the question goes like this:
If one day while walking in a forest with two of your close friends, one friend shows you an elephant and tells that this is a rhino, and another friend shows you a hippopotamus and tells you that this is rhino, who would you believe and why?
I told you that you do not know what a rhino looks like, not that you are unaware of what a hippo and elephant look like. So you shouldn't believe either of them.
