Answer:
Bottles collected by Section A = 9 ½ kg ; section B = 7 ⅓ kg ; C= 8¾ kg.
Average = Sum of collection/ 3
9½+ 7⅓ + 8¾ / 3
Method A : 9.5+8.75+7.34/3
25.59/3
8.53 kg.
Method B : 9½ = 19/2 ; 7⅓ = 22/3 ; 8¾ = 35/4
(19/2 + 22/3 + 35/4) ÷ 3
(19×6 + 22×4 + 35×3/12) ÷3
(114+88+105/12) ÷3
(307/12) ÷ 3
307/36
8 19/36 kg.
