An artist moves along a hexagonal path of each side 20 m in such a way that for the first 20m he goes with the speed of 20m/s and the next 20 m with the speed of 10m/s.Similarly he continues for the rest of the hexagonal path with the same alternating speeds,i.e,20m/s and 10m/s.The average speed of the artist per round of the circus is: Ans is 13.33
Digits of two three digit numbers are coded with the help of alphabets. It is
A B C
+ A C B
B C A
All alphabets represent unique digits.
What is value of unit digit of B-C?
A and B are natural no.s such that AB+1 is divisible by 24.Which of the following will definitely divide A+B?
N is a natural no.2N is having 28 factors, and 3N is having 30 factors. How many factors 6N will have?
N=2^8 * 3^10 * 5^8 * 7^2.What is the no. of factors of this number N which are multiples of 360 but not multiples of 540?
A three digit no. is such that number of factors of the original number=Number of factors of the new no. made by reversing the digits(Left one at the right one and vice versa).If the middle no.(Tens place digit)=5, how many such no.s exist?
in chess, a knight moves two squares in one direction and one square in another direction,ending up on the diagonally opposite corner of a 2*3 grid.intervening squares can be occupied.find the maximum number of knights which can be placed on an 8*8 chess board so that no knight threatens another knight(can move into a square occupied by one of the other knights).
