Explanation:

- You are given three 2-digit numbers, pp, qq, and rr, with the condition that pp + qq + rr = tt0, a multiple of 10.

- Statement 1: To find potential values for p, note that the sum must end in 0. By systematically checking possibilities, you will find 5 values for p that satisfy the condition.

- Statement 2: For q, with p and r having certain constraints and ensuring the sum ends in 0, you will find 6 possible values for q that meet these conditions.

- Both statements are verified and correct.

Answer: Option 3 - Both 1 and 2
