Let’s solve it step-by-step in simple and copyable format.
🔹 Given:
- Mr. V travels 2400 km per month
- Mileage = 18 km per litre
- Petrol price before hike = ₹112 per litre
- Petrol price after 8% hike = ?
- Need to find how many km to reduce to keep petrol expenditure same
Step 1: Petrol used for 2400 km
Petrol needed = 2400 ÷ 18 = 133.33 litres
Step 2: Monthly petrol cost before price hike
Cost = 133.33 litres × ₹112 = ₹14,933.33
Step 3: Petrol price after 8% hike
New price = 112 + (8% of 112) = 112 + 8.96 = ₹120.96 per litre
Step 4: Let new distance travelled = x km
Then petrol used = x ÷ 18 litres
New cost = (x ÷ 18) × 120.96
We want this equal to old cost (₹14,933.33):
(x ÷ 18) × 120.96 = 14,933.33
→ x = (14,933.33 × 18) ÷ 120.96
→ x ≈ 2234.43 km
Step 5: Reduction in travel distance
Original = 2400 km
New = 2234.43 km
Reduction = 2400 - 2234.43 ≈ 165.57 km
✅ Final Answer: Mr. V needs to reduce travel by approximately 166 km ✅
