Answer 1

1 + 2= 21 2+3= 36 3+4 =43 4+5 = 58

Solution:

According to question,

1 + 2 =21 , 2 +3= 36 and 3+4 =43      

And we have to find 4+5 = ?

Let us determine the logic used here:

a + b  = ba + 0 or 4 alternatively

1 + 2 = 21 + 0 = 21

2 + 3 = 32 + 4 = 36

3 + 4 = 43 + 0 = 43

4 + 5 = 54 + 4 = 58

Thus 4 + 5 = 58
