Question

The mean weight of four apples is 250 g. If
two apples of weight 280 g each are added to
the group, what is the mean weight of the six
apples?(data handling) ​

Answer 1

MEAN=TOTAL WEIGHTS/NO.OF ITEMS

123 =x/10

1230=x

x is the addition of WEIGHTS of 10 apples

after adding 2 apples

no. of apples =12

MEAN=TOTAL WEIGHTS/NO. OF ITEMS

121=y/12

121×12=y

1452=y

y is the addition of weights of 12 apples

y-x=1452-1230

222...

THE WEIGHTS OF 2 APPLES IS 222GMS
