Question

The mean of 12 numbers is 30.If 3 is subtracted fron each no.,what will be the new mean.

Answer 1

MEAN IS 30

NO. ARE 12

SO SUM WILL BE 30*12= 360

NO. ARE 12

WE SHOULD SUBSTRACT 3 FROM EACH NO

MEANS 12*3= 36

SO SUBSTRACTING 36 FROM SUM....

360-36= 324

THE MEAN = NEW SUM / TOTAL NO.

THE MEAN = 324/12

THE MEAN = 27

SO THE NEW MEAN = 27.....
