The average weight of 47 balls is 4 g. if the weight of the bag (in which the balls are kept) be included; the calculated average weight per ball increases by 0.3 g. What is the weight of the bag?

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)

18.4 ans

Rajesh sarkar :Don't add bag as 48th item

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

18.4 is the answer

18.4 instead

Don't include 1 in denominator for the bag calculating the new average

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

Sorry misread the statement 14.1 is correct ans👍

I think ans is to be 18.4 instead of 14.1

Plzz explain the ans why ans is 14.1
