did not get the answer
The arithmetic mean of 20 numbers was wrongly calculated due to misinterpretation of 5 numbers. The average of wrongly taken 5 numbers was increased by 12 (from their original value) due to an error. Find out the change to be done on the calculated arithmetic mean of 20 numbers to get the real average.
