Total increased weight
= 0.3 × 47
= 14.1 g
Bag weight= 0.7 g (.4+.3=.7 g)
Total Bag weight= 14.1+0.7= 14.8 g (Ans)

4+(47+1)*0.3=18.4

Ans should be 18.4
Avg weight= total weight/Total no
4=Tw/47
Tw=188
Now including avg weight 0.3 with 4 is = 4.3
48*4.3= 206.4
So, weight of the bag is 206.4-188= 18.4

total increment in weight is due to bag only
per ball .3 gm increment
for 47 balls its
0.3*47=14.1
