Answer 1

Step-by-step explanation:

total run scored in 10 innings = 21.5×10= 215

total run he must score after 11 innings= 24×11= 264.

he must score in 11th Innings= 264-215= 49.

Answer 2

Answer:

The answer is 49.

Step-by-step explanation:

Number of innings played by crikcketer = 10 innings

Average runs in 10 innings = 21.5 Runs  

Therefore, Number of runs in 10 in innings = 10×21.5 = 215 Runs  

Here we need to find number of runs the cricketer must take in next innings to rise his average to 24.

Let x be the number of runs in 11 innings and assume that average is 24

therefore,  Average of 11 innings runs = (215+x)/ 11 = 24

                                     ⇒   $\frac{215+x}{11} = 24$  

                                     ⇒ 215+x = 24×11

                                     ⇒ 215+x = 264

                                     ⇒ x = 264 - 215 = 49

therefore, required runs is 49.
