(d) Rs. 27​

Answer 1

Answer:

b) Rs.17

Step-by-step explanation:

total amount of mixture = 16+5=21

cost of kerosene = Rs 12 per liter

therefore for 16 liters it is 12×16=Rs 192

cost of petrol = Rs 33 per liter

therefore for 5 liters of petrol it costs 33×5=165

now total cost of mixture is 165+192=357

cost of 1 liter of mixture = total cost of mixture ÷ total number of liters = 357÷21= Rs17
