• A. Rs. 60
• B. Rs. 65
• C. Rs. 70
• D. Rs. 75

Hint:

Multiply quantities by prices and sum for total cost in such problems.

Answer 1

The Correct Option is A

- Step 1: Cost of pens = $3 \times 10 = 30$.
- Step 2: Cost of pencils = $4 \times 5 = 20$.
- Step 3: Cost of erasers = $5 \times 2 = 10$.
- Step 4: Total cost = $30 + 20 + 10 = 60$.
- Step 5: Verify: Recalculate each item and sum: Matches 60.
- Step 6: Option (1) is correct.
