since 11284 and 7655 leave the same remainder assume [ begin{array}{l} 1284=P times Q_{1}+R quad text { and } 7655=P times Q_{1}+R end{array} ] Where ( P ) is me number (3-digit) with which they are divided, ( Q_{1} & Q_{2} ) are restaditiders, quotients and R is the remainder [ begin{aligned} P_{x}left(Q_{1}-Q_{2}right) &=3629 P timesleft(Q_{2}-0,1right) &=191 times 19 end{aligned} ] no. leanonly and fackor of since ( p ) is ( # begin{array}{c}2-d i g text { it } text { be ceval to } 191end{array} ) 3629 it can ohily Sum of digik ( =9+1+1=11 )
