The average weight of an apple in a sample of 10 apples was calculated as 104 g. Later on, it was found that the weighing had shown the weight of each apple 20 g less. The correct average weight of an apple in that sample is: Correct Answer 124 g

Given:

The average weight of an apple in a sample of 10 apples was calculated as 104 g.

Formula used:

Average = Sum of observation/Total number of observation

Calculation:

Sum of the weight of 10 apples before an error

⇒ 104 × 10

⇒ 1040 gm

Change in apples weight = 1040 + 10 × 20

⇒ 1240 gm

Hence, Correct average weight

⇒ 1240/10

⇒ 124 gm

∴ The correct average is 124 gm.
