61
Step-by-step explanation:

2) Since the number is bigger than 50 and smaller than 100, we know the answer is going to be ranging in somewhere between 50 and 70
3) Now, we have to make sure the digits add up to 7, so no we are left we the options 52, 61, and 70
4) We have to make sure the answer is an odd number. Therefore, 61 is the correct answer.
