The answer should be 32 2/3. Sorry I'm late, but hope this helps.
Answer:
Price of paint = Rs 16,640
Step-by-step explanation:
As 3 dimensions are given so the third one must be for ceiling.
So in this case, we can find area as follows:
Area = 2(length * width) + 2(length * height)+ 2(height * width)........eq1
Lets say:
Length = 8m
Width = 6m
Height = 4m
So putting value in eq1 we get:
Area = 2(8*6) + 2(8*4) + 2(4*6)
Area = 2(48) + 2(32)+ 2(24)
Area =96 + 64 + 48
Area = 208 sq. m
Now for calculating price:
Price of paint = 208 * 80
Price of paint = Rs 16,640
I hope it will help you!
We're going to be using combination since this question is asking how many different combinations of 10 people can be selected from a set of 23.
We would only use permutation if the order of the people in the committee mattered, which it seems it doesn't.
Formula for combination:

Where
represents the number of objects/people in the set and
represents the number of objects/people being chosen from the set
There are 23 people in the set and 10 people being chosen from the set


Usually I would prefer solving such fractions by hand instead of a calculator, but factorials can result in large numbers and there is too much multiplication. Using a calculator, we get

Thus, there are 1,144,066 different 10 person committees that can be selected from a pool of 23 people. Let me know if you need any clarifications, thanks!

The options are wrong lol, it is -1/8
we are given that
3 chickens to lay 32 eggs
now, we can find number of eggs per chicken
number of eggs per chicken= (total eggs)/(total chicken)
so, we get
number of eggs per chicken is

now, we can set up following
1.5 chicken : 1.5 eggs : 1.5 days
3 chickens : 3 eggs : 1.5 days
1 chicken : 1 egg : 1.5 days
Since, changing number of chicken won't affect time
time to lay eggs will always remain same
so,
for 1 chicken to lay
eggs
it takes
