The correct answers are:
(1) If EXACT number is required, then 7.5.
(2) If multiple of 8 is required then the answer will be 7 times with a remainder of 4.
Explanation:
First you need to express it in the form of equation to make things simpler as follows:
8 * y = 60
We need to find y; to do so, divide 60 by 8:
y = 
y = 7.5
Now if you want to find the whole number, then the answer will be 7 times, with 4 left over.
The digit in the ten thousands place is printed slightly to the left
of the one in the thousands place.
If they are the same digit, then the value of the one on the left is
ten times the value of the one on the right.

Answer:
∑E(x
) = 13.49167 floors
Step-by-step explanation:
The expected number of floors no one get off = ∑E(x
) where i is from 0 to 23
and E(x
) = ∑x
P(x
)
here x
is the indicator of floor where no one gets off, its value is 0 when atleast one person get off on its floor and 1 when when no one gets off.
Now,
P(x
=1) = (22/23)¹²
P(x
=0) = [1-(22/23)¹²]
Now,
E(x
) = ∑x
P(x
) = 0* [1-(22/23)¹²] + 1*(22/23)¹² =0.586594704
For total number of floors where no one gets off
∑E(x
) = E(x₁)+E(x₂)+E(x₃)........................+E(x₂₃)
∑E(x
) = 23*0.586594704
∑E(x
) = 13.49167 floors
