Question

2 and 7 = 65, 6 and 9 = 233, 3 and 4 = 130, then 8 and 5 = ?

Answer 1

Value of 8 and 5 is 306.

Solution:

A series of numbers are given to determine how their respective results are formed as we can see that the numbers are 2 and 7 = 65

Now how did 2 and 7 give out 65, let us check  

If we add 2 and 7 we get 9 and square it and then add it with 7 we get 130 which is the result of 3 and 4 but if we follow the same procedure for 3 and 4 we get 65 it seems the solution is interchangeable and alternate  

$\begin{array}{l}{(2+7)^{2}+7^{2}=130} \\ {(3+4)^{2}+4^{2}=65}\end{array}$

So following the same procedure for all we get  

$\begin{array}{l}{(6+9)^{2}+9^{2}=306} \\ {(5+8)^{2}+8^{2}=233}\end{array}$

Therefore, as the value are interchanging that means as real answer of 6 and 9 = 306 but after interchanging it becomes 233, then the value of 8 and 5 = 306.
