Question

Tolong ya nomor 35.

Answer 1

Pensil
= 120°/40° x 18 lusin
= 3 x 18
= 54 lusin

spidol
= 60°/40° x 18 lusin
= 3/2 x 18
= 27 lusin

sudut pulpen
= 360 - 40 - 120 - 60
= 140°

pulpen
= 140°/40° x 18 lusin
= 7/2 x 18
= 63 lusin

Answer 2

Jumlah buku = 18
jumlah pensil = (120/40) x 18 = 54
jumlah spidol = (60/120) x 54 = 27
jumlah pulpen = (140/60) x 27 = 63

maka rata2 = (18+54+27+63)/4 = 162/4 =40,5
