Answer: 45
Step-by-step explanation:
Harsh is part of a school cricket team, and he has scored an average of 46 runs in 5 innings. His scores in 4 of them are 46,45, 39, and 55. His fifth score is calculated as follows:
Since he made 5 innings and has an average of 46, the total scores will be:
= 46 × 5
= 230
Total of his first 4 scores will be:
= 46 + 45 + 39 + 55
= 185
5th score = 230 - 185
= 45
Answer: his score on the last one is 45.
Step-by-step explanation:
Let h represent the his score on the last inning.
Average number of runs = sum of runs/total number of innings played.
From the information given,
Average number of runs = 46
total number of innings played = 5
Sum of runs= 46 + 45 + 39 + 55 + h = 185 + h
Therefore,
46 = (185 + h)/5
Cross multiplying by 5, it becomes
46 × 5 = 185 + h
230 = 185 + h
h = 230 - 185
h = 45
