If (13^3+14^3+15^3+16^3+17^3+....34^3) is divided by 35. Then what will be the reminder

The arithmetic mean of the nine numbers in the set {9,99,999.....,999999999} is a 9-digit number M , all of whose digits are distinct. The number M does not contain the digit?

A dog after travelling 50 km meets a swami who counsels him to go slower.He then proceeds at 3/4th of his formal speed and arrives 35 min late.Had the meeting occured 24 km further the dog would have reached the destination 25 mins late.The speed of the dog is?

letters of word" ATTEMPT" are written down at random, find the probability that all the T's are together?

There are five sets of digits – Set A, Set B, Set C, Set D and Set E as shown in given

diagram. Set A contains one digit, Set B contains two digits, Set C contains three digits, Set D contains two

digits, and Set E contains one digit.

Rearrange the digits, across the sets, such that the number formed out of digits of Set C is a multiple of the

numbers formed from digits in sets on either side. For example; in the given diagram, SET C is a multiple of

digits in SET A and SET B but not of SET D and SET E.


SET A SET B SET C SET D SET E

7 28 196 34 5



28. What is the minimum number of rearrangements required to arrive at the solution? A rearrangement is

defined as an exchange of positions between digits across two set00 For example: When 1 from set C

is exchanged with 5 of set E, it is counted as one rearrangement.

A. 5 B. 2 C. 8 D. 3 E. 7

29. Which of the following pair of digits would occupy set A and E?

A. 2 and 6 B. 3 and 6 C. 3 and 9 D. 4 and 8 E. 2 and 4

Then he sells half of the balance eggs and another half an egg to Shivani. In the end he is left with just 7 eggs and he claims that he never broke an egg. How many eggs did he start with ?

Find the number of prime factors of 1000027?


a) 2 b) 3 c) 4 d) None of these

For a positive integer i define p(i) as the product of base 4 digits of i e.g. 27 in base 4 is 123 => p(27) = 1*2*3 = 6.

What is the numerical value of p(1) + p(2) + p(3) + ... + p(255)?

@cristianokaka

A teacher asks the students to find the average of nine 3-digit natural numbers. A student named BHAI MERE mistakenly reads the digits of one of the nine numbers in reverse order and gets an average which is 33 more than the actual average. How many distinct values are possible for the number which was incorrectly read by the BHAI MERE?

@cristianokaka tu itne question lata kahan se hai?


How many 5 digit numbers can be created if the following terms apply: the leftmost digit is even, the second is odd, the third is a non even prime and the fourth and fifth are two random digits not used before in the number?(last digit are different )

A group of workers having equal efficiency can complete a job in 4 days. But it so happens that on every alternate day starting from the second day, 3 workers are withdrawn from the job and every alternate day starting from the third day, 2 workers are added to the group. If it now takes 7 days to complete the job, find the no. of workers who started the job?

A and B working alone can do a certain piece of work in 40 days and 120 days respectively. A and B start working together on that work but after having worked for 10 days, the work is increased. The additional work is such that B would take 40 days working alone to complete it. In order to cope with additional load, C is introduced and the remaining work is finished in 5 days. Find the number of days that C alone would take to complete the original work.

Find the remainder when [(2 × 4 × 6 × 8 × 10 ×…× 200) – (1 × 3 × 5 × 7 × 9 ×…× 199)] is divided by 201.

A cyclist left point A for point B and travelled at the constant speed of 25km/h. when he covered the distance of 8.33 km, he was overtaken by a car that left point A twelve minutes after the cyclist and travelled at a constant speed too. When the cyclist travelled another 30km, he encountered the car returning from B. Assume that the car did nt stop at point B. Find the distance b/w A and B.
