Question

since 11284 and 7655 leave the same remainder
[
begin{array}{l}
text { assume } 1284=P times Q_{1}+R text { and }
qquad 2655=P x Q+R
end{array}
]
Where ( P ) is me number (3-digit) with which they are divided, ( Q_{1} ) & ( Q_{2} ) are retwatioders, quotients and ( R ) is the nemainder
[
begin{aligned}
P xleft(Q_{1}-Q_{2}right) &=3629
P timesleft(Q_{2}-0,1right) &=191 times 19
end{aligned}
]
since ( p ) is ( k a ) s-digit no. pomondy and fachor ( z ) 3629 it can ohily be equal to ( mid 91 ). ( operatorname{sum} delta f operatorname{dig}^{prime}(x)=9+|+|=1 mid )
