tolong ya kak n maaf tulisanku kaya ceker ayam

Diketahui :
Rata-rata seluruh = 77
Banyak siswa = 36
Pria = 79
Wanita = 76

= 77×36 = 2772
= 79 pria ( p) + 76 wanita (w)
= 79 (36 - w ) + 76 w
= 2844 - 79 p + 76 w

= 2772 - 2844 = -3

• W = - 72 = - 3 w
= 72 ÷ 3 = 24 wanita

• P = 36-w
= 36-24 = 12 pria

Jadi,
Pria : 12
Wanita : 24

Good luck
