The average score of Dhoni after 48 innings is 48, and in the 49th innings, Dhoni scores 97 runs. In the 50th innings, the minimum number of runs required to increase his average score by 2, then it was before the 50th innings: 48টি ইনিংসের পর ধোনির গড় রান 48। 49তম ইনিংসে ধোনি 97 রান করে। 50তম ইনিংসে গড় রান আগের ইনিংসের তুলনায় 2 বাড়াতে হলে ন্যূনতম কত রান করতে হবে?

Average after 48 innings = 48

\[ \text{Total runs after 48 innings} = 48 \times 48 = 2304 \]

49th innings score = 97

\[ \text{Total after 49 innings} = 2304 + 97 = 2401 \]

Average after 49 innings:

\[ \frac{2401}{49} = 49 \]

He wants to increase the average by 2 in the 50th innings.

New average required = \( 49 + 2 = 51 \)

\[ \text{Total runs required after 50 innings} = 50 \times 51 = 2550 \]

Let the 50th innings score be \( x \).

\[ 2401 + x = 2550 \]

\[ x = 149 \]

Correct Answer: Option B
