Answer 1

Answer:

The corrected average income will be 169.2 INR

Step-by-step explanation:

the average income of a group of 50 persons working in a factory is calculated to be inr. 169

Average = 169 INR

Number of Person = 50

Total Income = 169 * 50  =  8450 INR

one of the figures was taken to be 134 instead of the correct value 144

=> 134 need to be decreased & 144 Need to added

Total Income =  8450 - 134 + 144  = 8460

Average = 8460/50 = 169.2 INR

The corrected average income will be 169.2 INR
