  2. Step-by-step explanation:

    for division by 5

    a) N = 0,5

    for N=0

    M+5+6+0= multiple of 3

    11+M= multiple of 3

    M is a digit having value from 0 to 9

    11+M has value from 11 to 20

    11+M=12,15,18

    M =1,4,7

    for N=5

    M+5+6+5= mutiple of 3

    M+16=mutiple of 3

    M+16 has value from 16 to 25

    M+16=18,21,24

    M=2,5,8

    b)

    N=0,5 for divisibility by 5

    N=0

    M+4+5+7+0=multiple of 3

    M+16= multiple of 3

    M+16 has value from 16 to 25

    M+16=18,21,24

    M=2,5,8

    for N=5

    M+4+5+7+5= multiple of 3

    M+21= multiple of 3

    M+21 has value from 21 to 30

    M+21=21,24,27,30

    M=0,3,6,9

    c)

    M=0,5

    for M=0

    N+6+0+8+0= multiple of 3

    N+14=multiple of 3

    N+14 has value from 14 to 23

    N+14=15 ,18,21

    N=1,4,7

    for M=5

    N+6+0+8+5= multiple of 3

    N+19= multiple of 3

    N+19 has value from 19 to 28

    N+19 =21,24,27

    N=2,5,8
