Answer:

7th digit =2

Step-by-step explanation:

Let the six digits be a,b,c,d,e,and f

Given,

Average of six digits=8

a+b+c+d+e+f/2=8-------eq1

a+b+c+d+e+f=8×2

a+b+c+d+e+f=16

Also,given that if one more digit is added to eq1 then the value would be 10

a+b+c+d+e+f/2+g=10

16/2+g=10

8+g=10

g=10-8

g=2

The seventh digit=2
