Question

The number of lifeguards with orange vests is between 4 Tens and 6 Tens. The number of lifeguards with green vests is between 5 Ones and 7 Ones. Which of the following options makes the total number of lifeguards?

• A. 45 + 5 = 50
• B. 9 + 15 = 24
• C. 50 + 6 = 56
• D. 40 + 5 = 45

Answer 1

The correct option is C 50 + 6 = 56

Detailed step-by-step solution:
Since the number of lifeguards with orange vests is between 4 Tens and 6 Tens, it will be 5 Tens, i.e., 50. And the number of lifeguards with green vests is between 5 Ones and 7 Ones, therefore it will be 6 Ones, i.e., 6.
Therefore, the total number of lifeguards = 50 + 6

Hence, Option D is correct.
