koushik singha  (9 years ago)

as given AB is odd,so A,&B must be odd no.
now for AD is odd, so D is also odd.
now for FACG is odd,F,A,C,G also odd.
now for C+DE is also odd, and we know C and D is odd. so E must be Even.
So A,B,C,D,F,G are odd and E is even.
(N.B:you can easily understand if you think it by taking some numerical value)

odd*odd=odd; so AB both are odd
as AD=odd,so D will be odd as well,
coming to next FACG=odd;so each of them should be odd.
But in second option its given that C+DE=ODD.....(1) ;(before we got C & D both are Odd)
so given (1) equation will be odd when E will be even.
Ans:-Only E is the even integer and rest are ODD.
