Question

There are 50 workers in a factory. Their mean wage was calculated at ₹12,000. Later on it was

discovered that the wages of two workers were misread as 15,000 and 20,000 in place of 14,000 and

12, 000. Find the correct average.​

Answer 1

Explanation:

50workers mean average = ₹12000

two people misread as 15000 and 20000 but was 14000

so 50 x 12000 - 20000+15000/50

600000-35000/50

mean average =11300
