Detailed Solution
Download Solution PDFGiven:
Petrol quantity = 10 litres
Petrol cost per litre = ₹105
Kerosene quantity = 15 litres
Kerosene cost per litre = ₹25
Formula used:
Price of mixture = \(\dfrac{\text{Total cost}}{\text{Total quantity}}\)
Calculation:
Total cost = (Petrol quantity × Petrol cost per litre) + (Kerosene quantity × Kerosene cost per litre)
⇒ Total cost = (10 × 105) + (15 × 25)
⇒ Total cost = 1050 + 375
⇒ Total cost = ₹1425
Total quantity = Petrol quantity + Kerosene quantity
⇒ Total quantity = 10 + 15
⇒ Total quantity = 25 litres
Price of mixture = \(\dfrac{1425}{25}\)
⇒ Price of mixture = ₹57/litre
∴ The correct answer is option (1).
