    Solution

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