Ex 8.6 Class 6 Maths Question 6. Namita travels 20 km 50 m every day. Out of this she travels
10 km 200 m by bus and the rest by auto. How much distance does she travel by auto?

_______
Therefore Namita travelled 9.850 km by auto
Ex 8.6 Class 6 Maths Question 7. Aakash bought vegetables weighing 10 kg. Out of this, 3 kg 500 g is onions, 2 kg 75 g is tomatoes and the rest is potatoes. What is the weight of the potatoes?
