Correct Answer - Option 2 : 39.8
GIVEN:
There are five prime numbers between 30 and 50
FORMULA USED:
Average = (Sum of the observation)/Number of observation
CALCULATION:
Prime numbers between 30 and 50 are 31, 37, 41, 43, and 47
⇒ Average = (Sum of the observation)/Number of observation
⇒ Average = (31 + 37 + 41 + 43 + 47)/5
⇒ 199/5
⇒ 39.8
∴ Average of all prime numbers b/w 30 and 50 is 39.8
