Question

# Let X be the set of first 100 natural numbers. Sets S1 and S2 are subsets of X such that each of them has more than zero elements and no common element. If the maximum number of elements in S1 = x1, in S2 = y1 and minimum no. of elements in S1 = x2, in S2 = y2 then: If |x1 - y1| and |x2 - y2| are at their minimum possible values then which of the following is true?

Solution

## The correct option is B |x1 - x2| = |y1 - y2| The minimum possible value of |y1 - y2| = 1 - 1 = 0. The minimum possible value of |x1 - x2| = 99 - 99 = 0. So, |x1 - x2| = |y1 - y2|. Hence, option (b) is correct.
