Answer 1

It's a trick question, you can't know the answer. If the sandwich choice and drink choice are independent, they don't depend on each other, so it could be anywhere from 0-90 people

Answer 2

60 of the people who ordered the spicy fried chicken sandwich got a chocolate milk.

Explanation:

Consider the provided information.

60 people order the grilled chicken sandwich, and 90 people order the spicy fried chicken sandwich.

40 Out of 60 people who order grilled chicken sandwich got a chocolate milk to drink.

Let say x number of people out of 90 got chocolate milk drink.

Now we need to find the people who ordered the spicy fried chicken sandwich got a chocolate milk.

The above information can be written as:

`(40)/(60)=(x)/(90)`

`(40)/(60)* 90=x`

`x=20* 3`

`x=60`

Hence, 60 of the people who ordered the spicy fried chicken sandwich got a chocolate milk.
