n1=35, total mass, m1 = 35*49 = 1715
n2=8, total mass, m2 = 8*53 = 424
Total bag count = n1+n2
total mass = m1+m2
New mean mass = (m1+m2)/(n1+n2)
n2=8, total mass, m2 = 8*53 = 424
Total bag count = n1+n2
total mass = m1+m2
New mean mass = (m1+m2)/(n1+n2)

So does that mean
n1=35
n2=8
m1=1715
m2=424
Total bag count: 43
Total Mass: 2139
New mean mass: 49.74418605
Round it to the nearest kilo
50kg.
Is that correct???
