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?

Solution:

Distance travelled by Namita daily = 20 km 50 m or 20.050 km

Distance travelled by her by bus = 10 km 200 m or 10.200 km

∴ Distance travelled by her by auto = (20.050 – 10.200) km = 9.850 km

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?

Solution:

Weight of vegetables bought by Aakash = 10 kg

Weight of onions bought by him = 3 kg 500 g

= 3.500 kg

and weight of tomatoes bought by him = 2 kg 75 g = 2.075 kg

∴ Weight of potatoes = Weight of vegetable – (weight of onions + weight of tomatoes)

= 10.000 – (3.500 + 2.075)

= 10.000 – 5.575 = 4.425 kg
