    I think that the number is 35 because I used a 100 number grid and I went through the clues to get 35

    35 could be the answer.
    This is because it is greater than 9, it’s not a multiple of ten , it is a multiple of 7, the number is odd, it is not a multiple of 11, it is less than 200, the ones digit is larger than the tens digit, the tens digit is odd. I know this because 35 is higher than nine, it cannot be a multiple of ten because multiples of ten end with a zero, it is a multiple of 7 because 7 times 5 is 35, the number is odd because the numbers 1,3,5,7,9 are odd and 5 is an odd number so 35 is odd,it is not a multiple of 11 because the me of 11 are 11, 22, 33, 44 (and so on) and 35 is not there, the ones digit is 5 and the tens digit is 3 so the ones digit is bigger, 3 is the tens digit and three is odd.

    35 because it is a greater than 9.It is not a multiple of 10. But it is a multiple of 7. It is odd and not a multiple of 11. The ones digit is larger than the tens. The tens is odd.

      Hi Usman,
      Look at each of the clues and find the number which satisfies each clue. There are 8 clues in total but some are more relevant than others.
