Q. find the remainder when 54^124 is divided by 17?
a.4
b.5
c.13
d15

Reply Like? Yes (1) | No

Kushagra Tiwari 10 years ago

54 and 17 are co prime.. hence we can use euler's theorem..
16 is the euler no for 17.. hence [(54^16)^7]/17 gives remainder 1
hence we have to find the remainder of 54^12/17 => 3^12/17 => 9^6/17 => 2^18/17 => [4*(2^4)^4]/17=> remainder is 4

Initially it produces 10 sounds and the defect came and now it produces only 2 different sounds and consecutively so there are totally 2 sounds and we have to select on sound and the probability is ½ and it produces the same sound concecutively for 2 times so the probability becomes ½*1/2 ie ¼

11. There are two boxes, one containing 10 red balls and the other containing 10 green balls. You
are allowed to move the balls between the boxes so that when you choose a box at random and a
ball at random from the chosen box, the probability of getting a red ball is maximized. This
maximum probability is?

Reply Like? Yes | No

Kushagra Tiwari 10 years ago

the probability for selecting red box is 1/2 but randomly if we select green box, the probability will be 0.
so, total probability for this case is 0.5.

now consider the other case, 9 red balls are transferred to green ball box. now total balls in that box will be 19.

total probability = probability to select 1st box + probability to select 2nd box

= (1/2)*(1C1/1C1)+(1/2)*(9C1/19C1)

= (1/2)*(1+9/19)

= (1/2)*(28/19)

= 14/19

A permutation is often represented by the cycles it has. For example, if we permute the numbers in the natural order to 2 3 1 5 4, this is represented as (1 3 2) (5 4). In this the (132) says that the first number has gone to the position 3, the third number has gone to the position 2, and the second number has gone to position 1, and (5 4) means that the fifth number has gone to position 4 and the fourth number has gone to position 5. The numbers with brackets are to be read cyclically.
If a number has not changed position, it is kept as a single cycle. Thus 5 2 1 3 4 is represented as (1345)(2).
We may apply permutations on itself If we apply the permutation (132)(54) once, we get 2 3 1 5 4. If we apply it again, we get 3 1 2 4 5 , or (1 2 3)(4) (5)
If we consider the permutation of 7 numbers (1457)(263), what is its order (how many times must it be applied before the numbers appear in their original order)?
a. 12
b. 7
c. 7! (factorial of 7)
d. 14

Devendra Marghade 10 years ago

56 hours

*considering 'overnight' & 'overtime' mentioned here is same then,
Basic pay/hour of week= 200/40 =5 Rs.
Overtime pay/hour=(125/100)*5=25/4 Rs.
If man works for 'x' extra hours in a week & considering all working hours more than 40 as overtime, then
40*5 +(25/4)*x=300 , x=16
So total hours he worked=40+16= 56

Ex: 4*4=16

325^325/125^n
325^325 = 325*325*325.................325 times
and 125 = 5*5*5
also 325 = 5*5*13 (2 fives)
in 325 times 325 we have 5^(2*325) which we can write in (5^3)^216
so the answer is 216

explain anyone this term-- we have 5^(2*325) which we can write in (5^3)^216

Reply Like? Yes | No

Dikesh Kumar Gumansingh 10 years ago

5^(2*325)=5^650
(5^3)^216=5^648
but if we put 217 instead of 216...it'll be 651>650
so we took 650

perimeter of the triangle is : 25+11+31= 67
perimeter of the square is : 4*side which will be equal to perimeter of the triangle
so, 4*side=67
=> side=16.75
since the area of the square will be : side*side
=> 16.75*16.75 = 280.5625
i.e. option (A) is correct

How many positive integers less than 10,000 are there in which the sum of the digits equals 5?

Reply Like? Yes | No

Anand Dwivedi 10 years ago

I believe the answer to be C: 56.

Basically, the question asks how many 4 digit numbers (including those in the form 0XXX, 00XX, and 000X) have digits which add up to 5. Think about the question this way: we know that there is a total of 5 to be spread among the 4 digits, we just have to determine the number of ways it can be spread.

Let X represent a sum of 1, and | represent a seperator between two digits. As a result, we will have 5 X's (digits add up to the 5), and 3 |'s (3 digit seperators).

So, for example:

XX|X|X|X = 2111
||XXX|XX = 0032

etc.

There are 8C3 ways to determine where to place the separators. Hence, the answer is 8C3 = 56.
