For any multiple independent event, there are n^m

total possible outcomes, where n is the number of outcomes per event, and m is the number of such events.

So for a coin, discounting the unlikely event of landing on its side, there are two possible outcomes per event, heads or tails. And it is stated that there are 3 such events. So n^m=2³=8

.

Total Distance = 10 +12 = 22 km
Total time = 10/12 + 12/10 = 5/6 + 6/5 = 25/30 + 36/30 = 61/30 hours
Average speed = 22 /(61/30) = 660/61 = 10.8 km/ hour

Let the ages of children be x, (x + 3), (x + 6), (x + 9) and (x + 12) years.
Then, x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50
 5x = 20
x = 4.
Age of the youngest child = x = 4 years.

The three white flags can be arranged in the following two ways:
__ W __ W __ W or W __ W __ W __
In the blanks, the 2 blue and one red flag can be arranged in 3 ways.
So, the total number of arrangements is 2*3 = 6

20% of a = b  => (20/100)a = b
b% of 20 =(b/100) x 20 = (20a/100) x (1/100) x (20) = 4a/100 = 4% of a.

Let's assume the original two - digit number is represented by "AB," where A represents the tens digit and B represents the units digit.
According to the given in formation, we know that the number obtained by interchanging the two digits is less th the original number by 18.
This can be represented by the equation : (10A+B)−(10B+A)=18
Simplifying this equation, we get : 10A+B−10 B−A=18
9A−9B=18
A−B=2 (dividing both sides by 9 )
We also know that the sum of the two digits is 16 :
A+B=16
Now we have a system of equations :
A−B=2A+B=16​
Solving these equations simultaneously will give us the values of A and B. Adding the two equations, we get :
2A=18⇒A=9
Substituting the value of B back into one of the equations, we find: 9+B=16⇒B=7
Therefore, the original number is 97 .

Add all the numbers in the set:
302+152+132+122+112 = 820.
Divide the sum (820) by the number of elements in the set (5):
820÷5 = 164.

nC₃ - _n-1C2 = 84, where n is the number of students. Now use options.

They are all the first letters of the numbers spelt in order.
O – One
T – Two
T – Three
F – Four
F – Five
S – Six
S – Seven
E – Eight
N – Nine
So the answer is N

Short cut formula: The total number of person =  Position of Ganesh from the right ends + Position of Ganesh from the left ends – 1
Now, Position of Ganesh from the right ends = The total number of person – Position of Ganesh from the left ends + 1
= 60 – 26 + 1 = 35.
Hence, Ganesh is 35th from the right ends.
 

Mrs. Abraham can’t be sitting next to him as per the seating arrangement. Wives sit three places away from their husbands.
Mrs. Charlie is sitting to the left of Mr. Abraham. So, she can’t be sitting to his right.
Mrs. Elenor is sitting two places to the right of Mrs. Border (and not Mrs. Charlie). So, she can’t be sitting right next to Mr. Abraham.
Mrs. Border and Mrs. Dennis are the remaining two wives and each is equally likely to to be sitting to the right of Mr. Abraham.

Two drain pipes can drain the same volume that one fill pipe fills. This means that a D-D-F combination has to have a net volume effect of 0.
In spite of this, the tank still gets filled. Only the fill pipes can manage to fill the tank. In addition to all the net zero effect pipes, we need three more fill pipes in order to fill the tank in 2 hours.
So, we can have as many D-D-Fs as we want, but we need one F-F-F at the end to ensure that the tank gets filled in 2 hours.
So the number of pipes will be → (D – D - F).......(D – D - F) + (F – F - F).
The number of pipes has to be a multiple of 3. Only options (a), (c) and (e) fit the description.
The question is "How many of the following values could ‘n’ take?"
Hence, the answer is 3.

Angle traced by hour hand in 12 hrs  =360^∘
Angle traced by hour hand in 5 hrs 10 min. i.e.,

According to the given statements, Statement II states that there has been a huge dropout from the primary schools in rural areas. This suggests that the high dropout rate is the cause. Statement I states that a large number of Primary Schools in rural areas are run by only one teacher. This implies that the lack of sufficient teachers may be the effect of the high dropout rate, as fewer students remaining in schools would require fewer teachers. Therefore, Statement II is the cause, and Statement I is its effect. The correct answer is option b) Statement I is the cause, and statement II is its effect.

2×3=6
3×4=12
4×5=20
5×6=30
6×7=42
7×8=56
8×9=72
The numbers in the series are in order as shown above.
After 42 , the next number in series should be 56 instead of 54 . Hence, the odd number is 54

To find the total number of persons in the row, we can use the formula:
Total number of persons = Position of Alex from the right end + Position of Alex from the left end - 1
U sing the given information,
we have: Position of Alex from the right end =412 Position of Alex from
the left end =285
Substituting these values into the formula :
Total number of persons =412+285−1
Total number of persons =696
Hence, the total number of persons in the row is 696 .
