let the number be abc

1) N is multiple of 20
there are so many three-digit multiples of 20
insuff

2)The hundreds digit of N is 6 more than the units digit
if number is 721, hundreds digit is 7
but if number is 872, or it can be 600
insuff

combined
we know it is multiple of 20, so units digit is 0
but hundreds digit is 6 more , so 0+6=6
suff

N= 100a + 10b+ c
so
#1
N multiple of 20 ; tens place is always 2,4,6,8,0 and units 0 always
hundreds can be 1,2,3,..9
notsufficient
#2
The hundreds digit of N is 6 more than the units digit
it can be any value again insufficient
from 1& 2
we know multiple of 20 units is always 0 so hundereds is 0+6 ; 6
IMO C
