<PRE><B>Question 951691</B>
2 stroke motor fuel has unleaded petrol and a special oil mixed in a ratio 50:1

4 stroke motor fuel has unleaded petrol and oil in a ratio 25: 1
------------------------
 
QUESTION: If you mixed 20 litres of 2 stroke fuel with 20 litres of 4 stroke fuel, what would be the ratio of unleaded petrol to oil in the combined mix?--------------------
Equation:
oil + oil = oil
20*1 + 20*2 = 60 litres of oil
---
petrol + petrol = petrol
20*19 + 20*18 = 740 litres of petrol
-----
Answer:: 740:60 = 74:6 = 37:3
