Answer / mohammed ayaz khan

As we know standard weight of wall putty= 849kg/cum

example:
vol of wall putty= area of wall putty x thickness of wall(the thickness of wall putty always 3mm i.e 0.003) take 10sq.m as example of area of wall putty

= 10x0.003
= 0.003 cu.m

standard wt of wall putty=849kg/cu.m

=standard wt of wall putty x volume of putty

= 849 x 0.003=2.54kgs And the avg of wall putty always( 5,10,20,40 kgs )

total bags = 2.54/5= 0.50 (half bag of wall putty)

1 bag of wally putty is 1200 rupees
