if ,
7+8=94
5+4=51
4+9=23
8+4=42
then ,

6+7=??

• the ans is 63.
  
  first the digit is multiply
  
  7*8=56
  
  then subtract the first term from the 56.
  
  56-7=49
  
  After that make the reverse of the number so ans is 94.
  
  similarly
  
  5*4=20
  20-5=15
  reverse 51
  
  4*9=36
  36-4=32
  Reverse = 23
  
  so 6*7=42
  42-6=36
  
  so Reverse= 63

• step to be followed:
  (1) 1st multiply both given no
  (2) subtract the first number from multiplication
  (3) reverse the no.
  As for example: (1) 7*8=56
  (2) 56-7=49
  (3) reverse this 49 then 94
  so in the same trend for all so for 6+7:
  (1)6*7=42
  (2)42-6=36
  (3)63
  so required answer is 63.
