Any number can be expressed of the form: 9K+i; where k= {0,1,2,....} and i={0,1,...,8}
Now, we have to select numbers from {1,2,...,3000} in a manner so that final set does not contain any two numbers whose sum is divisible by 9. We have to identify the maximum size of such selection.
Now, within 1 to 3000,
#elements of the form 9k+1 = 334.

Now, within 1 to 3000,
#elements of the form 9k+1 = 334.
#elements of the form 9k+2 = 334.
#elements of the form 9k+3 = 334.
#elements of the form 9k+4 = 333.
#elements of the form 9k+5 = 333.
#elements of the form 9k+6 = 333.
#elements of the form 9k+7 = 333.
#elements of the form 9k+8 = 333.
#elements of the form 9k = 333.
Now, as per condition, if you select any number from the group 9k+i then you can not select number from the group 9k+j where i+j=9.
So, in order to maximize the size of selection, you will go for group:
9K+1, 9k+2,9K+3 and 9k+4. So, total (334+334+334+333=1335).
Now, you can select exactly one number from the group 9K. (More than one will result their sum divisible by 9).
So, total becomes 1336.
Now, you have to exclude 1 (from group 9k+1) and 3000 (from group 9k+3).
So finally you are with 1334 numbers! «less

18k- my fees (-non negotiable ) /course completed in 3 months/ daily classes/-100% coverage + 24*7 doubt clearing.
Study material + test series = Rs. 4-12 k (all are same)
Total expense = 18+ (4-12)= Rs. 22k to 30k.
elsewhere you would be spending from Rs. 25k to 55k depending upon location and institute that too you would have access to only one study material.

The first n natural numbers, 1 to n, have to be arranged in a row from left to right. The n numbers are arranged such that there are an odd number of numbers between any two even numbers as well as between any two odd numbers. If the number of ways in which this can be done is 72, then find the value of n?

0 0 3

Correction:-
It is (n-1)/2 ! * (N+1)/2 !
So if n is 7 then answer is 144
If n is 5 then answer is 12.

It needs to be visualized first that there can be only 1 odd number between any two even numbers and vice versa
because if you place 3 odd numbers between 2 even numbers then some pair of even numbers will not have any odd numbers between them

It needs to be visualized first that there can be only 1 odd number between any two even numbers and vice versa

lets assume a set of numbers
1, 2, 3, 4, 5, 6
2, 1 ,3 ,5 ,4 ,6 not satisfying the condition
thus we have only 2 of types possibility that satisfies the given condition:
1 2 3 4 5 6
2 1 4 3 6 5
the two types of possibility happened because the number of odd and number of even numbers are same
but for a set of odd numbers there will be only one type of possibility i.e. starting with odd numbers.
e.g.:-
2 3 4 5 1 not satisfying the condition
1 2 3 4 5
Now coming to the question.
Lets suppose,
n is even and thus n=2t+2 (where t is an integar with t>0)
thus t+1 even numbers and t+1 odd numbers
2*(t+1)! (t+1)! = 72
(t+1)! = 6
t = 2
n = 6.
Lets suppose
n is odd and thus n=2t+1 (where t is an integar with t>0)
thus t even numbers and t+1 odd numbers
(2t+1)! (t)! = 72
for t=1 rhs =6
for t=2 rhs =240
thus the above equation will not be satisfied for any value of t.
Hence, n = 6 «less

Theoretically, you need 3 equations to solve linear equations with 3 variables. In this question, you are given only two equations with three variables. That means this problem comes under special equations. Depending upon the nature of the equations you have to apply special technique to solve special equation.

Since a bucket holds 5 litres of water, Tap A discharges 20 litres of water in 24 minutes or 5/6 litres of water in 1 minute.
Tap B discharges 40 litres in 1 hours or 2/3 litres in 1 minute.
Tap C discharges 10 litres in 20 minutes or 1/2 litres in 1 minute.

Ice Gate replied | 17/12/2016

The more relevant thing in this case is not the number of strikes but the number of time intervals.
If a clock has to strike 4, there are 3 time intervals between the 4 strikes So, in 7 seconds the pendulum elapses 3 time intervals.
To strike 11, there has to be 10 time intervals, which will take (10 x 7)/3 = 23.33 seconds.

Let the CP of the article be Rs. x, since he earns a profit of 20%, hence SP= X + 20% of X = 1.2x.
