Answer
23

The correct answer is 23 — 17 + 6 = 23. Because adding 17 and 6 gives 23.

Step-by-step solution

  1. Add the number of marbles Sita initially has (10) to the number she bought (7). Because the problem asks for the total after the purchase.
  2. 10 + 7 = 17. Then add the marbles she found (6) to this intermediate sum. Because the final total must include all marbles she possesses.
  3. 17 + 6 = 23. Because adding 17 and 6 gives 23.
