Answer 1

Answer:

20% as 50% doesnt know to read and write

Answer 2

Answer:

The third number will be 14 and considering the literacy rate and difficulty of question, I thinks 20% population can solve it.

Step-by-step explanation:

As per the data given in the question,

We have two numbers which is 3 and 7.

Also, it is given that their average is 8.

Lets assume the third number be $x$

$\frac{x+3+7}{3}=8 \\x=24-10\\x=14$

So, the third number will be 14

Now, considering the literacy rate and difficulty of question, I thinks 20% population can solve it.
