If I think like this,
From option two, 4+1+2=7 which is the last digit of the number
Option three, 5+2+1=8 Which also the last digit of the number
And the last option, 7+0+1=8 Which represents the last digit as well
In this way A could be the correct Answer.
a nd b both
It is also (A)3229 because sum of 1st three number is 8 expect option A...
Option A is also correct adding first 3 digits got last one
Also sum of 1st 3 digit is equal to last so 1st is rit also
Aslo A can be the ans. As, in other options last digit is equal to sum of 1st 3
There is another logic which support option
(a )correct
Sum of 1st three number is equal to the last number
I.e. 7+o+1=8
5+2+1=8
what is the correct logic as the sum of ist 3 digits is equal to 3rd digit
there is another suggestion too, which makes a) 3229 correct.
all numbet except 3229 have last digit = sum of first three.
eg. 4127 - -> 4+1+2= 7
eg. 5218 - - > 5+2+1= 8
