Measurement - 2 - Free MCQ Practice Test with solutions, Class 3 Mathematics

The relationship is based on units and their conversions:

• Metre (m) is to kilometre (km) as gram (g) is to kilogram (kg).
• This is because both conversions involve multiplying the base unit by 1,000.
• Thus, the correct answer is kg.

The solution is to determine who has the largest step among the children based on the number of steps taken to measure the room's width.

• Each child's individual step length is inversely related to the number of steps they took.
• The fewer steps a child took, the larger their step must be.
• After comparing the steps, it's clear that Saurabh took the fewest steps, indicating he has the largest step size.

1 km = 1000 m; 2 rounds = 2 km
⇒ 1 round = 1 km = 1000 m.

The shortest route is walking straight from the school to the bus stand. Amisha will cover 4 units, i.e. 4 x 250 = 1000 m.

Match the length of the objects with approximate measurement.

A spring balance is the most appropriate tool to measure weight of objects.

Pan A has 150 grams of weight which is less than the weight kept on Pan B 225 grams.

Pan B has 575 grams of weight which is more than the weight kept on Pan A 525 grams.

Pan B has 500 + 550 = 1050 grams Pan A has 750 grams; we need to add 1050 - 750 = 300 grams.

 Pan A has 2 + 2 = 4 kg Pan B has 1 kg; we need to add 4 -1 = 3 kg.
