The average (arithmetic mean) of five numbers is 5. If 2 is subtracted from each of four of the numbers, what is the new average?	Pick.
A) 3.4 B) 4.5 C) 6.2 D) 5.7 E) 6.9
Let the numbers be a , b, c , d , e ,f   So, Total of these 5 numbers must be 25   Or, a + b + c + d + e = 25   So, 12 must be subtracted from the total sum   i.e a + b + c + d + e - 8   Or, 25 - 8 = 17   Hence average of the 5 numbers now is  17/5=

<output>17/5 = around 3.4</output>
&gt;3.4   So, 3.4nswer will be 3.4
