Explanation:

- Calculate \( P_1 \): Find the average of prime numbers below 12. The primes are 2, 3, 5, 7, 11. The average is \((2 + 3 + 5 + 7 + 11)/5 = 28/5 = 5.6\).

- Calculate \( P_2 \): Find the average of prime numbers between 12 and 30. The primes are 13, 17, 19, 23, 29. The average is \((13 + 17 + 19 + 23 + 29)/5 = 101/5 = 20.2\).

- Calculate \( 5P_1 - P_2 \): Substitute the values. \( 5 \times 5.6 - 20.2 = 28 - 20.2 = 7.8\).

- Verify Options:

- Option 1: 7.8

- Option 2: 8.6

- Option 3: 9.8

- Option 4: 7.5

- Correct Answer: Option 1: 7.8
