Question

what is the value of M & N respectively?
if M39048458N is divisible by 8 & 11; where M & N
are single digit integer.

Answer 1

For a number to be divisible by 8, we check if the number formed by its last three digits (hundreds, tens and ones) is divisible by 8 or not

so we check for what value of N is 58N divisible by 8
so we start by checking for 580
580 divided by 8 = 72.5
so logically 73 x 8 = 584 is divisible by 8
so N = 4

Answer 2

for division by 8, value of M can be anything from 1 to 9

Answer 3

but the second condition is also given that the no should be divisible by 11 also

Answer 4

for M39048458N to be divisible by 11, the difference of the sums of alternate digits should be either zero or a multiple of 11
taking sum of alternate digits (starting from the ones digit)
since we already know that N=4
SUM I = N+5+8+0+3 = 4+16 = 20
SUM II = 8+4+4+9+M = M+25
difference SUM II - SUM I = (M+25) - 20 = M+25-20 = M+5
if difference = 0, then M+5 = 0 or M = -5 which is not possible
if difference is 11, then M+5 = 11 or M = 6 which is workable

so M = 6 and N=4
