Give kudos if you like question


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
