Answer 1

I'm thinking the answer is b. 9

because 3(4),5(6),7(8),9

I am not sure though since I didn't use the numbers inside.

Answer 2

Answer:

The answer is 8.

Step-by-step explanation:

According to my logic,

Like we take 82; so tens digit of 82 is 8.

And on both the sides of 82 is 5 , 3

Then if we add 5+3 = 8

And 8 is also the unit digit of 82.

Similarly,

Like we take 122; so first 2 digit of 122 is 12.

And on both the sides of 122 is 5,7

Then if we add 5+7 = 12

==> 12 is also the first 2 digit of 122.

Similarly,

Like we take 115; so first 2 digit of 115 is 11.

And on both the sides of 115 is 3 , ?

Then if we add 3 + ? = 11  ---(1)

Similarly,

Like we take 151; so first 2 digit of 151 is 15.

And on both the sides of 151 is 7 , ?

Then if we add 7 + ? = 15 ---(2)

Subtracting (2) from (1),

We get 8.

So the required answer is 8.

∴ You can also check by putting 8 in (1) and (2).
