B

The sum of the "other" 2 numbers is 14, plus 7 = 21

Very tricky question!!
(1) 16 can be 7+9 or 6+10 hence sum can be 7+9+some unknown which can be any of the rest hence INSUFFI

(2)14 will be sum of any numbers other than 7 since 7,7 cannot be numbers only one slip is numbered 7 => 7+14 =21 is the sum ANSWERS
SUFFI

IMO B
