Question

How many numbers are divisible by 3 between 50 and 500?

• A. 150
• B. 149
• C. 151
• D. 160

Hint:

For counting numbers divisible by a number in a range, use the formula: (last - first)/divisor + 1.

Answer 1

The Correct Option is A

First number divisible by 3 ≥ 50 is 51; last ≤ 500 is 498. Number of terms in sequence: (498 - 51)/3 + 1 = 147 + 1 = 148 + 1 = 150. Thus, the correct answer is: \[ {\text{150}} \]
