Question

If $S_2$ denotes the sum of elements of $D_2$ , then minimum value of $S_2$ is -

Answer 1

Solution

The question is incomplete as $D_2$ is not defined. Assuming $D_2$ is a set of distinct positive integers, the minimum sum $S_2$ is achieved by choosing the smallest distinct positive integers. If $D_2 = \{1, 2\}$ , then $S_2 = 1+2 = 3$ . This matches one of the given options.
