1.
The only numbers whose digits have a sum of 15 and a difference of 1 are 78 and 87. Since 95 - 8 = 87, the second sentence eliminates 87 as a possibility. Therefore, the number is 78.
2.
The only numbers with two odd digits that sum to 10 are 19, 37, 55, 73, and 91. The only one of these choices in which the tens digit minus the ones digit equals 4 is 73. Therefore, the number is 73.
