Question 915813
Let the hundreds digit = {{{ h }}}
Let the units digit  = {{{ u }}}
The tens digit = {{{ 8 }}}
-----------------------
They are all different
(1) {{{ 8 = 3u - 4 }}}
(1) {{{ 3u = 12 }}}
(1) {{{ u = 4 }}}
--------------
(2) {{{ h + 2u = 11 }}}
(2) {{{ h + 2*4 = 11 }}}
(2) {{{ h = 11 - 8 }}}
(2) {{{ h = 3 }}}
---------------
The number is: 384
-----------------
check:
{{{ 384/3 = 128 }}}
{{{ 384/4 = 96 }}}
It is less than {{{ 400 }}}
{{{ 384 / ( 2^7 ) = 384/128 }}}
{{{ 384/128 = 3 }}}
OK
