x < 35 + 35 + 15x < 85x > 40 x 2x > 80Therefore x is between 81 to 84 (inclusive).The only number in this range in which the digits sum to 9 is 81.

If seven less than half of the number is 35 then 7 plus 35 must be half of the number. 7 + 35 = 42 and if that is half the number the whole number must be 42 x 2, which is 84.
The secret number must be a two-digit number greater than 25 and less than 50. Since the tens digit is odd, it can be 3, 5, or 7. However, the sum of the digits must be less than 10, so the only possible tens digit is 3. The units digit can be any number from 0 to 9 that, when added to 3, results in a sum less than 10. Therefore, the secret number is 31.

x < 35 + 35 + 15x < 85x > 40 x 2x > 80Therefore x is between 81 to 84 (inclusive).The only number in this range in which the digits sum to 9 is 81.
35 is a deficient number because the sum of its proper divisors is less than the number itself.

If the sum of all a number's factors (apart from itself) is equal to the original number, then the number is perfect. If this sum is less than the number, it is deficient. If the sum is more than the number, it is abundant. The factors of 70 are: 1, 2, 5, 7, 10, 14, 35 and 70. 1+2+5+7+10+14+35 = 74. Thus the number 70 is abundant.

If seven less than half of the number is 35 then 7 plus 35 must be half of the number. 7 + 35 = 42 and if that is half the number the whole number must be 42 x 2, which is 84.
Prime number which is greater than 30 and less than 35 is 31.
