Question

A farmer counted the banana of 482 banana trees of his field. the average no. of bananas was 3420. if the counting of bananas of one tree was written as 3573 instead of 3483 then find the correct average no. of bananas up to two decimal places.

Answer 1

The correct average is 3419.813

Step-by-step explanation:

Number of banana trees in the field = 482

Given average number of bananas in all the tress = 3420

Number of bananas with the given average = (Average) $\times$ (Number of banana trees in the field )

Therefore, Number of bananas = 482 $\times$ 3420

Incorrect counting of bananas of one tree = 3573 instead of 3483

Change of correction =3573 - 3483 = 90

Change of correction with respect to all the banana trees = $\frac{90}{482}$ = 0.18

When there is incorrect counting of an entity, we need to subtract it from the average in order to find the correct overall average.

Therefore, the correct average = 3420 - 0.1867 = 3419.813
