Show Hint
Nishi has 5 coins each of different denomination. The number of different sums of money she can form is ____.
Updated On: Apr 15, 2026
- 32
- 25
- 31
- None of these
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Each coin can either be selected or not selected (2 choices).
Step 2: Combinations
For 5 coins, total combinations $= 2^5 = 32$.
Step 3: Constraint
We must exclude the case where no coins are selected (sum = 0).
Step 4: Conclusion
Total sums $= 32 - 1 = 31$.
Final Answer: (C)
