Answer
Correct Answer: 90
Explanation
Given data
- Total amount = Rs. 480
- Three denominations: Rs. 1, Rs. 5, Rs. 10
- Counts equal ⇒ let each count be x.
Concept / Approach
- Total value = 1·x + 5·x + 10·x = 16x.
Step-by-step calculation
16x = 480 ⇒ x = 480 ÷ 16 = 30Total number of notes = 3x = 90
Verification
Value check: 30×1 + 30×5 + 30×10 = 30 + 150 + 300 = 480.
Common pitfalls
- Taking 480 ÷ 3 to get x (ignores denomination values).
Final Answer
Total notes = 90.
