The average wages of 500 workers were found to be Rs. 200. Later on , it was discovered that the wages of two workers were misread as 180 and 20 instead of 80 and 220.The correct average wages are:

Explanation:

500 workers → average wages is 200

Total wages = 200×500=100000

correct read 80+220=300 misread 180+20=200

+ Rs.100 is difference between correct wages and misread wages so we will add this in 1,00,000 and then divided by 500 then we find average wages

=1,00,100\500=200.20
