1.	A Batsman In His 18th Innings Makes A Score Of 150 Runs And There By Increasing His Average By 6. Find His Average After 18th Innings?
Answer» Let the average for 17 INNINGS is X RUNS Total runs in 17 innings = 17X Total runs in 18 innings = 17x + 150 Average of 18 innings = 17x + 150/18 17x + 150/18 = x + 6 -- > x = 42 Thus, average after 18 innings = 42. Let the average for 17 innings is x runs Total runs in 17 innings = 17x Total runs in 18 innings = 17x + 150 Average of 18 innings = 17x + 150/18 17x + 150/18 = x + 6 -- > x = 42 Thus, average after 18 innings = 42.

Let the average for 17 INNINGS is X RUNS

Total runs in 17 innings = 17X

Total runs in 18 innings = 17x + 150

Average of 18 innings = 17x + 150/18

17x + 150/18 = x + 6 -- > x = 42

Thus, average after 18 innings = 42.

Let the average for 17 innings is x runs

Total runs in 17 innings = 17x

Total runs in 18 innings = 17x + 150

Average of 18 innings = 17x + 150/18

17x + 150/18 = x + 6 -- > x = 42

Thus, average after 18 innings = 42.
