DS: How much money do Vivek and Suman have together? I. Suman has Rs.20 less than Tarun. II. Vivek has Rs.30 more than Tarun.
AI alone is sufficient
BEither I or II is sufficient
CBoth statements together are insufficient
DBoth statements together are necessary
Answer & Solution
Correct answer: C. Both statements together are insufficient
1. From I: Suman = Tarun − 20; Tarun is unknown.
2. From II: Vivek = Tarun + 30; Tarun is still unknown.
3. Even together: Suman + Vivek = 2 × Tarun + 10. Without Tarun, we can't compute. Both together insufficient.
