Which positive integer is a multiple of 3 and less than double the square of 4?
کون سا مثبت عدد 3 کا ضرب ہے اور 4 کے مربع سے دوگنا کم ہے؟
- 12
- 18
- 24
- 30
Explanation
Step 1: Calculate the square of 4.
4^2 = 16
Step 2: Double the square of 4.
2×16=32
Step 3: Identify the positive integers that are multiples of 3 and less than 32.
The multiples of 3 below 32 are:
3,6,9,12,15,18,21,24,27,30
Step 4: Focus on the number 18.
18 is indeed a multiple of 3.
18 is less than 32 (which is double the square of 4).
Thus, 18 satisfies both conditions, making it one of the correct answers to the problem.
