- let units place be x..therefore tens place is x+5..
now the units place cant be equal to or greater than 5 for the tens place being 5 greater will defy the condition that the number is 2 digit..
therefore options are:
50 61 72 83 94
out of them only number satisfying sum to be 11 is 83
answer is 83 - 12 years agoHelpfull: Yes(0) No(0)
