Answer:42

Step-by-step explanation:

Let X be the sum of the six numbers

X/6=32

Multiple 6 by both sides

6*X/6=32*6

X=192

Therefore the sum of the six numbers is 192

Let you be the sum of five numbers

The mean reduce by 2 =32-2=32

Y/5=30

Multiple both sides by 5

5*Y/5=30*5

Y=150

Therefore the sum of the five numbers is 150

Therefore the number will be reduced by =192-150

=42
