option (b)let the 6 digit telephone number be A B C D E Ffrom statement (1) no useful information can be obtained to obtain a unique phone numberfrom statement (2), if the sum of 3 digits = 27 A+C+E=27, the the only possibility is that A=C=E=9. Also given that D=F=0 and B=5. hence the number is 959090. answer can be obtained based on statement (2) alone
