    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

    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
