1)Determine the smallest possible positive integer ‘x’ whose last decimal digit is 6 and if we erase this last digit i.e. 6 and put it before remaining digits we get 4 times ‘x’.
2)Two circles of unequal radii intersect in two distinct points P & Q. Line through P cuts first circle at A & second circle at B. Let M be the midpoint of line AB. If line MQ meets first circle at X & second at Z, then in what ratio M divides line XZ internally?
3)Find all sets of four real numbers such that: a)any three of them are equal & b)sum of any one out of four and the product of the other three is 2.
