Umurbaba Posted February 13, 2019 Posted February 13, 2019 There is a 4 digit number which spells like "abcd". Jack, John and James tries to find this number. Jack only know the range of the digits(biggest -smallest).John only knows a+b+c+d.James knows a*b*c*d. Jack says: I dont know all the digits but James doesn't either. James says: I dont know all the digits but John doesnt either. John says: I just found it and Jack should be just found it as well. What is the four digits ?
