Hey mate ^_^

Ignore 1st digit 

12 reverse 21+4=25

13 reverse 31+5=36

14 41+6=47

15 51+7=58

16 61+8=69

17 71+9=80

18 81+10=91

So, 91 is the answer.

Answer 2

If

212 = 25 (Take one digit From right=2 & Sum of all 2+1+2= 5) 25

213 = 36 (Take one digit From right=3 & Sum of all 2+1+3= 6) 36

214 = 47 (Take one digit From right=4 & Sum of all 2+1+4= 7) 47

215 = 58 (Take one digit From right=5 & Sum of all 2+1+5= 8) 58

216 = 69 (Take one digit From right=6 & Sum of all 2+1+6= 9) 69


then 218 =(Take one digit From right=8 & Sum of all 2+1+8= 11) 811
