what is answer ??? (Question: 259911.0 )

weight of bag = 47x0.3 = 14.1 gm ...right or wrong

Question:

The average weight of 47 balls is 10 gm. If the weight of the bag be included, the calculated average weight per ball increases by 0.3 gm. What is the weight of the bag?

Options:
A)

14.4 gm

B)

25.4 gm

C)

26.4 gm

D)

None of these

Solution:

Ans: (d)

Sum of weight of 47 balls = 10 × 47 = 470 gm

Average weight per ball increases.

But bag will not be included, as it is not the item of balls. So, answer is none of these.

Nope.. In the question they tells that the average weight of ball will increase. This is not possible. If bag is also included total average can increase, but not average of balls alone.

I think Right answer should be 24.4 as Avg of 47 items + 1 bag=10.3
therefore total sum of 48 items = 48x10.3=494.4
Thus , weight of bag would be = 494.4-470=24.4
