ATQ, Quantity of petrol in 360 litres of mixture = (5/9) × 360 = 200 litres So, quantity of diesel in 360 litres of mixture = 360 – 200 = 160 litres Quantity of mixture taken out = 0.075 × 360 = 27 litres Quantity of petrol in 27 litres of mixture = (5/9) × 27 = 15 litres So, quantity of diesel in 27 litres of mixture = 27 – 15 = 12 litres Therefore, required ratio = (200 – 15):(160 – 12 + 27) = 185:175 = 37:35
