New Public School has a circular layout. The school has teachers specializing in various subjects. All

classrooms of the school are equally spaced apart and located along its perimeter. Each teacher needs

to take 4 classes in a day. There is a strange rule. The first and last class has to be in the same class

roun. The other two classes have to be at two other distinct class rooms.

Ram is a math teacher. He never teaches two successive classes at two adjacent classrooms. How many distinct trips to class rooms are possible for Ram if there are 9 class rooms in the school?

In a day
First & last room should be same
Let's choose it arbitrarily, next class can be chosen in 6 ways
Because same room cannot be chosen & neighboring rooms are also not allowed
Round represntations of class: 1 2 3 4 5 6 7 8 9. 1....

Let first one be 1
Then second can be 3 4 5 6 7 8
For 3, third class can be any of 5 6 7 8
For 4, third class can be any of 2 6 7 8 9
For 5, third class can be any of 2 3 7 8 9
For 6, third class can be any of 2 3 4 8 9
For 7, third class can be any of 2 3 4 5 9
For 8, third class can be any of 2 3 4 5 6
For 9, third class can be any of 2 3 4 5 6 7
And fourth class will be again 1

So total possible classes keeping first class constant is: (4)+(5*5)+(6) = 35

Similarly first class can be changed in 9 ways => Total possible trips per day = 9*35 = 315

Please check puzzle dated 14.06.2021

If the capacity of a cylindrical tank is 4004 m^3 and the diameter of its base is 14 m, then find the depth of the tank?

Solution given is
Let the depth of the tank be h meter
πr²h = 4004
h = 4004/ πr²
h = (4004 x 7/22 x 1/14)
h = 91 m.

I think admin has considered 2r =14 only in place of r^2 ( 7^2).

It should be

Let the depth of the tank be h meter
πr²h = 4004
h = 4004/ πr²
h = (4004 x 7/22 x 1/49)
h = 26 m.

Please check and do justice to maths.

Let the speed of the train be x m/sec and length of the train be y m, then y/x=11.3 or y - 11.3x = 0 --(i)
Also, (y + Length of platform)/x=18
(y+396)/x=18 => 18x-y=396 ---(ii)
Solving (i) & (ii), we get, x=59.10 and y=667.88

Average Visited in December = 2240
Then total visitors = 2240*31 = 69440
As there are 4 Thursdays and 4 Mondays the other 3 are Sunday,Friday and Saturday. It means 5 Sundays 5 Fridays and 5 Saturdays
It means 5*2240+5*2200+5*3000=11200+11000+15000=37200
Remaining=69440-37200=32240
Average of remaining=32240/16=2015

Let A and B are the persons.
A travelled x km,B travelled y km before they meet.
Time taken for A and B to reach their destinations are 10/3h,24/5h
Speeds are y/(10/3),x/(24/5)
At the time they meet they travelled same time => x/(3y/10)=y/5x/24)
10x/3y = 24y/5x=>50x^2=72y^2
=>x^2/y^2=72/50
x/y=√(1.44)=1.2
=>x=1.2y
Total distance =(x+y)=(x+x/1.2)=2.2x/1.2=11x/6
Now time taken for B=(11x/6)/(5x/24)
=11*24/6*5=44/5=8h 48m

If we diminish or expand any of the portions we eventually fall into same bucket I guess, so I think 31.5cm^2 should be the answer, all suggestions are welcome. Thanks.

We know that n! = n(n-1)(n-2)(n-3).....3(2)(1) which means that
n! = n(n-1)!
Dividing both sides of the equation by n, we have
(n - 1)! = n!/n
Using this fact, we can check the following pattern.
4! = 5!/5 = {(5)(4)(3)(2)(1)}/5 = 24
3! = 4!/4 = {(4)(3)(2)(1)}/4 = 6
2! = 3!/3 = {(3)(2)(1)}/3 = 2
1! = 2!/2 = {(2)(1)}/2=1

It is 210 and 300

Out of these candies with both maximum is 300. Since chocklet chips is subset to sprinkles.
60 is neither of them. So either of them are 500-60=440
Now minimum =350+300-440=210
So it will be 210 and 300

How many Kg ot wheat @ Rs. 14 per kg should be mixed with 32 kg of wheat @ Rs
22 per kg so that there is a profit of 25% by selling the mixture @ Rs 23.90 per kg

Reply Like? Yes | No (1)

Devendra Marghade 5 years ago

Ans: 18 kg

Let x kg of wheat costing Rs. 14/kg is mixed, then (x*14 + 32*22)/(x+32) = 23.9*(100/125)
(14x + 704) / (x+32) = 19.12
14x + 704 = 19.12x + 611.84
5.12x = 92.16
x = 18

Gold is 19 times as heavy as water and copper is 9 times as heavy as water. In
what ratio should these be mixed to get an alloy 15 times as heavy as water.

Reply Like? Yes (1) | No

Devendra Marghade 5 years ago

Required ratio = (15-9)/(19-15) = 6/4 = 3/2
Therefore, these should be mixed in the ratio 3:2.

Does anyone think that the prize system of today's puzzle needs to be changed and it needs to return the earlier system of distribution of prize amount. Whoever wants to win the prize needs to compete with other candidates. Otherwise there is no benefit of becoming topper of the week again if you already won a prize in a month.

Let the number of students be 'x' then x-1=6y and x-2=7z
=> 6y+1 = 7z+2 or 6y - 7z = 1
Which is true for y=6, z=5
So, minimum number of students=6y+1 or 7z+2 = 37

If two numbers are divided by a dividor produce remaindes 3 and 4, but then the sum of the numbers is divided by that divisor gives remainder 2. Find the divisor.

Reply Like? Yes (1) | No

Devendra Marghade 5 years ago

Ans=5

Let the divisor be a, first no. be x and second no. be y, then in given 3 conditions
X = ak + 3 —(i)
y = al + 4 —(ii)
x+y = am + 2 —(iii)
Adding (i) & (iii), and Substituting x+y in (iii), we get (ak+3) + (al+4) = am+2
a(m-k-l) = 5
Prime factorization gives a=5 or 1
As divisor cannot be 1 in above given conditions, so divisor a=5.
