Question

The average weight of six pupils in a class is 16.8kg . if the total weight of four of them is 70kg , what is the average weight of each of them remaining two assuming both have equal weight ?

Answer 1

Answer:

other two weights are 15.4kg

Step-by-step explanation:

let remaining two=x,x=2x

average=sum of total number/total no

16.8=2x+70/6

2x+70=16.8×6

2x+70=100.8

2x=100.8—70

2x=30.8

x=30.8/2

x=15.4kg
