Find Two-Digit Numbers: Tens Digit 6 and Less Than 67

To solve this problem, we need to identify the number that meets two conditions: having a tens digit of 6 and being less than 67.

First, let's list the numbers between 60 and 69, inclusive, that potentially have a tens digit of 6:

• $60, 61, 62, 63, 64, 65, 66, 67, 68, 69$

Next, we apply the constraint that the number must be less than 67. Re-evaluating our list, we focus on numbers less than 67:

• $60, 61, 62, 63, 64, 65, 66$

All these numbers have a tens digit of 6 and are less than 67.

The problem requires choosing one number, and among the answer choices provided, only 61 matches both conditions established (tens digit of 6 and less than 67).

Therefore, the solution to this problem is $61$, corresponding to choice id 2.
