Question

Medicine is packed in boxes, each weighing 4 kg 500g. How many such boxes can be loaded in a van which cannot carry beyond 800 kg?NCERT Class 6th Mathematics Chapter 1 Knowing our Numbers Exercise 1.2 Question 10

Answer 1

4kg=4×1000g=4000g
4kg+500g=4500g
maximum weight that van can load is 800kg=800×1000g=800000g
therefore maximum number of boxes are =
800000÷4500=177boxes

Answer 2

Answer:

The number of boxes that a van of 800 kg can hold is 177 boxes.

To find:  

The number of boxes that a van hold which cannot carry more than 800 kg.

Solution:

Weight of each box of medicine = 4 kg 500 g = 4000 g + 500 g = 4500 g.

Weight that the van can carry = 800 kg = 800 x 1000 g = 800000 g  

∴ No. of boxes that the van carry  

$= \frac {(800000 g)}{(4500 g)} =177.78$

$\approx 177 boxes$

Here, Quotient = 177                

[Remainder being 3500.]

Thus, the van can carry 177 boxes (approx.)
