Correct Answer: 45


Solution : Let his average before the 21 st match be $x$.
New average after 21 st match = $(x + 2)$
Total runs before the 21 st match = $20x$
Runs scored in the 21 st match = 87
⇒ $x + 2$ = $\frac{87 + 20x}{21}$
⇒ $21x + 42$ = $87 + 20x$
⇒ $x$ = $45$
Hence, the correct answer is 45.
