If the positive difference between the sum of even digits and odd digits (starting from unit's place) is divisible by 11, then the number is also divisible by 11.
(A) : 44433 = $$(3+4+4)-(3+4)=11-7=4$$
(B) : 45332 =Â $$(2+3+4)-(3+5)=9-8=1$$
(C) : 23581 =Â $$(1+5+2)-(8+3)=8-11=3$$
(D) :Â 59609 =Â $$(9+6+5)-(0+9)=20-9=11$$
In the above numbers, only in the last option, 11 is divisible by 11, hence 59609 is divisible by 11.
