a certain number of innings, the average runs scored by a batsman were 34. he scored 119 runs in the next innings and his average rose to 39.what is the total number of innings played by the batsman?
Answers
Answer:
the total number of innings played by the batsman = 80
Step-by-step explanation:
let, the total number of innings played by the batsman = x
the total runs scored by a batsman = 34x
now, total runs after he scored 119 runs = 34x+119
the average run = (34x+119)/(x+1),
39=(34x+119)/(x+1)
39(x+1)=34x+119
39x+39=34x+119
39x-34x=119-39
5x=80
x=80
Answer:
16+1=17 innings
Step-by-step explanation:
let the total no. of innings= x
Avg run=34
total run = 34×x =34x
in the next match= 119 runs
the new average is 39
total run after next match =34X + 119
total number of innings played after next match=x+1
total inning played by player= 34x+119/(x+1)=39
34x+119 =39x+39
34x-39x=39-119
-5x= -80 (- will cut both side)
x=80/5 =16 innings
