NCERT Class 6th Mathematics Chapter 1 Knowing our Numbers Exercise 1.2 Question 10

Answer 1

each box weighs  4kg 500g
van's limited is 800 kg 
 so number of boxes  = 800/4.5
  number of boxes   = 17.77777
  number of boxes   = 17

Answer 2

800 kg = 800 ×1000  = 800000 gm
4 kg 500 gm = 4× 1000 + 500 = 4500 gm
no. of boxes that can be carried in the van = 800000/ 4500
                                                                   = 177.78
                                                                   = 17.7 ( again convert it into kg)
that is 17 boxes
