What digit does A represent?

posted Jul 16, 2014

The digit A represent 7.

According to Divisibility rule for 8 last 3 digit should be divisible by 8 giving reminder zero, so "B" satisfies only with "2" (432/8=54).

And for 11, the difference of the sum of alternative digit should be zero or 11. To satisfy this condition "A" should be 7.

Thanks!!
