average weight of 47 balls is 4gm if the weight of the bag is included the calculated average weight per

total weight of balls excluding bag= (47*4)=188gms.
total weight of balls including bag=(4.3*48)=206.4gms.
therefore,the weight of the bag excluding balls=(206.4-188)=18.4gms

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

(a1+a2+a3+........a47)/47=4gm
(a1+a2+a3+..........a47+b)/47=A
A=4+0.3=4.3
(a1+a1+a3..........+a47)/47+b/47=4.3
4+b/47=4.3
b=.3*47=14.1

average weight of 47 balls is 4gm.if the weight of the bag is included,the calculated average weight per ball is increased by 0.3gm.what is the weight of bag?
