Question
24. (2) Total wages of 500 workers
[
=500 times 200=₹ 100000
]
( therefore ) New sum
[
begin{array}{l}
=(100000-180-20+80+220)
=₹ 100100
end{array}
]
Hence, new average wage
[
begin{array}{l}
=frac{text { New sum }}{text { Number of workers }}
=frac{100100}{500}=₹ 200.20
end{array}
]

24. The average wage of 500 workers was found to be *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 wage is (1) *200.10 (2) *200.20 (3) 200.50 (4) 201.00
