If a, b and c are integers, and a+b=c, is b a multiple of 7?
(1) a is a multiple of b.
(2) c is a multiple of 7.
(1) a is a multiple of b.
(2) c is a multiple of 7.
FROM STATEMENT - I ( INSUFFICIENT )
\(a = kb\)
So,\(a+b= kb + b = c\)
Or,\(b ( k + 1 ) = c\)
Since, b and k can take multiple values we can not be certain that b a multiple of 7
FROM STATEMENT - II ( INSUFFICIENT )
\(a+b = 7Kc\)
Since, b and k can take multiple values we can not be certain that b a multiple of 7
