Question

The amount used to purchase one litre of petrol can be used to purchase three liters of diesel or five liters of kerosene. Out of a certain amount, $510 is spent on diesel.

How much is spent on kerosene if equal volumes of three liquids are purchased with the total amount.

Help me!!!

Answer 1

p = price of kerosene/liter

5 p/3 = price of diesel

5 p = price of petrol

x = liters of diesel purchased

cost of x liters of diesel = 5 x p/3 = 510

cost of x liters of kerosene = x p

but x p = (3/5)(510) = 306
