Here is ur answer
No . of girls =53
Average weight =58 kg
Total weight =53×58 kg
=3074kg
Wrong weight of the girl =65
actual weight of the girl =45
Extra weight of the girl =65-45 kg
=20kg
so we subtract 20 kg from the total weight of all girls
=3074kg-20kg
=3054kg
Now,
Average weight =3054 ÷53kg
=57.6 kg
Thus , the average weight is 57.6 kg
