The average of 45 results was calculated as 27 but later it was found that while calculating 39 was taken as 93 by mistake, then what will be the correct average?
Average of 45 results = 27
=> Sum of 45 results = $$27\times45=1215$$
After correcting the mistake new sum = $$1215-93+39=1161$$
=> Correct average = $$\frac{1161}{45}=25.8$$
=> Ans - (A)
