Question

The average weight of 47 balls is 4 gm. if the weight of the bag (in which the balls are kept) be included, the calculated average weight per ball increases by 0.3 gm. what is the weight of the bag?

Answer 1

no. of balls = 47

average weight of balls = 4 gm

weight of the ball if kept in the bag = 0.3 gm

therefore, the weight of the bag = 4 gm X 0.3 gm = 1.2 gm

                                                      = 47 balls X 1.2 gm = 56.4 gm

therefore 56.4 gm is the weight of the bag

Answer 2

Answer:

The correct answer of this question is  18.1 grams.

Explanation:

Given - The average weight of 47 balls is 4 gm. if the weight of the bag is included, the calculated average weight per ball increases by 0.3 gm.

To find - what is the weight of the bag.

The average weight of 47 balls is 4 grams.

Added the average weight of each ball increased by 0.3 grams.

The weight of the ball has grown by 47 pounds is $47$ ×$0.3 = 14.1g$

Total weight of the bag = Average weight + Increased weight

Total weight of the bag = $4 + 14.1 g$

Total weight of the bag = 18.1 grams.
