Solution:

3.75 hours

Explanation:
While you can solve it as you like, a simple mathematical equation can be used to find out.
Let M be the amount of petrol initially.
Let N be the time for which they drove.
According to the question, the amount of petrol used by first car in N hours = MN / 4
The amount of petrol used by second car in N hours = MN / 5
Hence, the amount of petrol left in the first car = (M - MN / 4)
The amount of petrol left in the second car = (M - MN / 5)
AS per the details given in the question, we can form the below equation:
M - MN / 5 = 4(M - MN / 4)
N = 15 / 4 or 3.75 hours.
Hence, both the drivers have driven the car for 3.75 hours at that particular time.

Solution:

The probability is 5/36.

Event = {(1,5) , (2,4), (3,3), (4,2), (5,1)}
Therefore, P (getting sum = 6) = 5/36

Solution:

Solution:

Let us try to find average here.
The average number of hands per person among the people with one hand is 1 obviously.

Now in the remaining slot, half people have 1 arm and half have 2 arms. Therefore, the average arm per person is 1 only.

Now, if we combine both the results, we can conclude that the number of arms per person in that locality is 1.

Since the number of people living there is 200 in number, the number of arms will be 200 as well.
