Answer=24
Step-by-step explanation:
We need to have logical thinking skills to answer this question. We cannot answer it by simple subtraction.
Observe the seriers properly.
Let us assume that it is simple subtraction. 1 - 1 = 0. The equation is satisfied. So, we have to check the same for the remaining too. 2 - 1 = 1 but it is given as 3. So, simple subtraction is not the answer.
Come again to the first equation. The answer can be 1 x 1 - 1 = 0. It satisfies. Let us check it for the next. 2 x 1 - 1 = 1. No, it doesn't satisfy.
Let us try it again.
Square of 1 - 1 = 0. Yes, it satisfies.
Square of 2 - 1 = 4 - 1 = 3. It also satisfies.
Square of 3 - 1 = 9 - 1 = 8. It also satisfies.
So, square of 5 - 1 = 25 - 1 = 24. Is the answer
This can be done by trial and error method.
We can solve it easily if practice that kind of questions frequently
