Solve for x, where [ . ] represents greatest integer function and { . } represent fractional part function.
| [x] - 2x | = 4
[ x -1 ] + [ 1 - x] + x - {x} >0
| [x] + 2x| < 4
Given two straight lines x - y - 7 = 0 and x - y + 3 = 0. Equation of a line which divides the distance between them in the ratio 3 : 2 (internally) can be :
x - y - 3 = 0
x - y - 1 = 0
y = x
x - y + 1 = 0

Every body in a room shakes hands with everybody else. The total number of hand shakes is 66. The total number of person in the room is n
Last digit of n is 2
Sum of digit of n is 3
product of digit of n is 2
All of the above
Numbers of natural numbers smaller than ten thousand and divisible by 4 using the digits 0, 1, 2, 3 and 5 without repetition is n then
n = 31
n is divisible by 5
n is divisible by 3
