Question

If 3+4=3 4+4=35 5+4=4 6+4=12 7+4=60 Then 8+4=?

Answer 1

According to me, Ans will be 5

3+4=3 in this 
Multiply these 3 and 4 and when u get the two digit ans, square the both, higher digit square will be substracted by lower digit square
Now 3*4=12 
2^ - 1^ = 4-1=3
Here ^ is used by me as square
4+4=35
4*4=16
6^ - 1^=36-1=35
Solve all like this and finally
8+4
8*4=32
3^ - 2^=9-4=5
And 5 is ans
