There Are Two Sections A And B Of A Class, Consisting Of 36 And 44 Students Respectively. If The Average Weight Of Sections A Is 40 Kg And That Of Sections B Is 35 Kg. Find The Average Weight Of The Whole Class?

Answer»

TOTAL WEIGHT of (36+44) STUDENTS = (36x40+44x35) KG = 2980 kg.

AVERAGE weight of the whole class = (2980 / 80) = 37.25.

Total weight of (36+44) Students = (36x40+44x35) Kg = 2980 kg.

Average weight of the whole class = (2980 / 80) = 37.25.
