Village D has a tariff of ₹5 per unit for consumption up to 500 units per month and ₹6 per unit for consumption above 500 units per month. If 1 month = 4 weeks, what is the electricity bill for a household consuming 213.33 units per week?
- ₹3140
- ₹3340
- ₹3650
- ₹3440
Correct answer: ₹3340
Solution
Weekly consumption is 213.33 units, so monthly consumption is about 853.33 units. The bill is calculated slab-wise: 500 units at ₹5 and the remaining 353.33 units at ₹6. This gives the required total bill.
