The following bar chart shows the runs given and overs bowled by a bowler in 6 different matches.

Economy rate = $\frac{\text{Runs given}}{\text{Overs bowled}}$

What will be the economy rate of the bowler for all the 6 matches taken together? [Give your answer correct to 2 decimal places.]

6.12

Economy rate M1 = \(\frac{66 }{9}\)  = 7.33

Economy rate M2 = \(\frac{56 }{10}\) = 5.6

Economy rate M3 = \(\frac{72 }{8}\) = 9

Economy rate M4 = \(\frac{43 }{6}\) = 7.16

Economy rate M5 = \(\frac{20 }{8}\) = 2.5

Economy rate M6 = \(\frac{36 }{7}\) = 5.14

Economy rate for all 6 matches together = \(\frac{7.33+5.6+9+7.16+2.5+5.14 }{7}\) 

= 6.12     ( correct to 2 decimal places )
