    Solution

    Let the quantity of milk and water left in the jar be 7a litres and 3a litres, respectively According to the question, 7a – 3a = 70 => a = 17.5 Therefore, quantity of mixture left in the jar = 7a + 3a = 10a = 175 litres Therefore, quantity of mixture taken out = 250 – 175 = 75 litres => x = 75
