Answer:

A)80 I think this is correct answer

Answer 2

Answer:

Required value of value of 10-10 is 99.

So option B is the correct answer.

Step-by-step explanation:

Given,5 – 5 =24 and 7 – 7 =48

Now question is 10 – 10 =?

This is a problem of G.I.

If you notice this problem carefully then you can easily solve this.

This problem maintains a sequence.

i.e $n - n = {n}^{2} - 1$

Here,

$5 - 5 = {5}^{2} = 25$

and $25 - 1 = 24$

again $7 - 7 = {7}^{2} = 49$

and $49 - 1 = 48$

So,

$10 - 10 = {10}^{2} = 100$

and $100 - 1 = 99$

So value of 10-10 is 99.
