The correct average weight of the 6 people is 67 kg.

Given:

The average weight of 6 people is 64 kg.

One reading is wrongly noted as 35 instead of 53

To find:

Find the correct average weight  

Solution:

Formula used:

Average = [ Sum of observations ]/ [ Number of observations ]  

Sum of observations = [ Average ] × [ Number of observations ]  

From the data,

The average weight of 6 people is 64 kg.  

From the above formulas

Sum of 6 ages = 64 kg × 6 = 384 kg

Here, one of the weights 35 kg written instead of 53 kg

So to find the corrected total weight subtract 35 kg and add 53 kg

Corrected weight of 6 people = 384 kg - 35 kg + 53 kg = 402 kg

Corrected average = [ 402 kg]/6 = 67 kg

Therefore,

The correct average weight of the 6 people is 67 kg.
