Answer 1

$a.if \: the \: last \: digit \: is \: 0 \: or \: 5. \\ ex - 1495 \\ b.if \: the \: last \: two \: form \: a \: no. \: that \: \\ is \: divisible \: by \: 4. \\ ex - 8512 \\ c.If \: the \: difference \: of \: the \\ sum \: of \: alternative \\ digits \: of \: a \\ number \: is \: divisible \: by \: 11,$

$\\ then \: that \: number \: is \: divisible \: by \: \\ 11 \: completely. \\ ex - 9647 \\ d.Divisibility \: rule \: for \: 10 \: \\ states \: that \: any \: number \\ whose \: last \: digit \: is \: 0, \\ is \: divisible \: by \: 10. \\ ex - 100$
