Question
A tank contains petrol and diesel in the ratio 9:5. If
10% of the mixture is removed and replaced with diesel, what is the new ratio of petrol to diesel?Solution
Total quantity = 14x litres Petrol = 14x × (9/14) = 9x litres Petrol left = 9x × 0.9 = 8.1x litres Diesel = 14x - 8.1x = 5.9x litres Required ratio = 8.1x : 5.9x = 81 : 59
