№1.

$(abcd)+(bcda)+(cabc)+(ddab)=(1000a+100b+10c+d)+\\+(1000b+100c+10d+a)+(1000c+100a+10b+c)+\\+(1000d+100d+10a+b)=1000(a+b+c+d)+\\+100(a+b+c+d)+10(a+b+c+d)+(a+b+c+d)=\\=(a+b+c+d)(1000+100+10+1)=1111(a+b+c+d)=\\=1111*33=36663.$

Ответ: 36663.

№2.

Аналогично рассуждая, получаем, что

$(cabc)+(ddab)+(bcda)+(abcd)=1111(a+b+c+d)=39996;\\a+b+c+d=\frac{39996}{1111} =36.$

Ответ: 36.
