1 + 4 = 5
2 + 5 = 12
3 + 6 = 21
5 + 8 = ?
If we see all these equation we find a relation between all these.
Now, the first is 1+4=5, it is simple.
for the second eq we have to look at both 1st & 2nd eq. 1 + 4 =5
2+ 5 = 12.
if we add both the digits of eq separately like 1+2 & 4+5, then we get the result 3 & 9. And again add these two no 9+3=12.
Now for the 3rd eq,
1+4 = 5
2+5= 12
3+6 =21, again add 1+2+3 & 4+5+6, result is6 & 15. Then 15+6 = 21.
similarly, for 4th eq,
1+4=5
2+5=12
3+6 =21
5+8 = ?. add (1+2+3+5) & (4+5+6+8), their sum is 11 & 23. again to get answer follow the process & add 11+ 23 =34, which is final answer.
