{{{QPQP }}}


Find {{{B}}} and {{{C}}} 


for now, {{{C}}} could be any digit from {{{0-9}}}


{{{QPQP}}} => since it is 4-digit number,{{{ B}}} must be {{{5}}} when {{{C}}} is {{{0-9}}}


take a closer look at {{{QPQP}}}=>  1st and third digit  are same  , second and fourth digit are same 


since {{{B=5}}}, when adding tents we will have one to cary and add it to hundreds, so we will 
 
have {{{6+4=10}}}

then, we know=>{{{Q=1}}} and {{{P=0}}}; so, {{{QPQP=1010}}}


only if {{{C=3}}}, {{{B=5}}}, we will have {{{QPQP=1010}}}
