Explanation: Let's solve the problem step by step. **Let:** - \( A \) = Average after the 11th innings - \( T \) = Total runs after the 11th innings = \( 11A \) **After the 12th innings:** - The batsman scores 80 runs. - New total runs = \( T + 80 = 11A + 80 \) - New average = \( A + 3 \) **Setting up the equation for the new average:** \[ \frac{11A + 80}{12} = A + 3 \] **Multiply both sides by 12 to eliminate the denominator:** \[ 11A + 80 = 12(A + 3) \] \[ 11A + 80 = 12A + 36 \] **Rearrange to solve for \( A \):** \[ 80 - 36 = 12A - 11A \] \[ 44 = A \] **Now, find the new average after the 12th innings:** \[ \text{New average} = A + 3 = 44 + 3 = 47 \] **Final Answer:** \[ \boxed{47} \]
