7-5 = 2  but given that 7-5 = 71 
8-4 = 4  ------------------ 8-4 = 28
4-3 = 1  ------------------ 4-3 = 52
now if we add the digit ; for ex:  7-5 = 71  (7+1=8)
the difference is 6 from the real ans  ( 2+6 = 8)
similarly, in 8-4 = 28 (2+8=10)  8-4 = 4  (4+6 = 10)
hence(9-1 = 8)  now (8+6= 14)
∴ the ans is 86

 

1 5 1
I hope u can understand everywhere the differnce is 6 in the ans
Thanks for your explanation. Why it cant be 77 (7+7=14)?
same numbers should be there
btw....welcome.....
Thanks for the great explanation...
