Q. Find the average of all prime numbers between 30 and 50.
✅ Correct Answer: (A)
39.8
Explanation: Prime number-a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11).
Then the total prime number b/w 30 to 50=31,37,39,41,43,47
Now average=(31+37+39+41+43+47)/6=39.666667,
Approximate=39.8
Then the total prime number b/w 30 to 50=31,37,39,41,43,47
Now average=(31+37+39+41+43+47)/6=39.666667,
Approximate=39.8
