Question

1. There are 5 bags of wheat weighing on an average 102 Kgs. and another 8 bags weighing 98 Kgs. on an average. What is the combined mean of the 13 bags?
a) 45 Kgs
c) 98.75 Kgs.
b) 99.54 Kgs
d) 95.54 Kgs​

Answer 1

99.54

Step-by-step explanation:

total bags=13

102*5=510

98*8=784

and 510+812=1294

And if we divide it by 13 we would get 99.54

                                        (or)

5 bags weight 102kg

8bags weight 98kg

average maen = total weight /total no of bags

=5*102+8*98/(5+8)

=99.538is approx mately equal to 99.54

Therefore average mean =99.54
