Data Sufficiency — total money held by Vivek and Suman together Statements: I. Suman has ₹20 less than Tarun has. II. Vivek has ₹30 more than Tarun has. Choose the correct sufficiency option to determine (numerically) how much Vivek and Suman have together.

Difficulty: Easy

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient

Correct Answer: Neither I nor II is sufficient

Explanation:

Let Tarun have T rupees
From I: Suman = T − 20. From II: Vivek = T + 30.

Together
Vivek + Suman = (T + 30) + (T − 20) = 2T + 10. Since T is unknown, the total cannot be determined numerically.

Conclusion
Neither I nor II is sufficient to give a numeric total.
