Question

The mean of 6 numbers is 32. If one of
the number is excluded, the mean redures
by 2. Then find what is the excluded number?​

Answer 1

Answer:

42

Step-by-step explanation:

32 = x/6

6*32 = x

192 = x

new mean = 32-2 = 30

then , 30 = x/5

30*5 = x

150 = x

192-150 = 42

i hope it helps

Answer 2

Answer:

42

Step-by-step explanation:

let the 6 numbers be a,b,c,d,e,f

mean=32

a+b+c+d+e+f/6=32

a+b+c+d+e+f=192

if we assume f is excluded

a+b+c+d+e/5=30

a+b+c+d+e=150

solving both the equations

f=192-150=42
