FROM ONE 32/K GIVES A REMAINDER OF 8

K COULD BE 24 OR 12......SUFF

FROM TWO

42/K = 6 K COULD BE 36 OR 18 OR 12 OR 9 INSUFF

1. f(k+32)=8 is the remainder..so k+32-8 =k+24 is divisible...implies k+24 is divisible by k or say,24 is divisible by k...also k must be more than theremaionder 8...so for k>8 and k dividing 24...the possible value of k could be 12 and 24....hence k>10..

sufficient..

2. with same argument..36 should be divisible by k and k>6...value satisfying these,k=9,12,18,36..hence k>10 i not true always..

insufficient

hence choice a
