Question

Bantu yaa..
No 11 & no 12

Answer 1

P1 = 100  orang
h1 = 25 hari
p2 = 100 orang
h2 = 15 hari
p3 = 100 - 50 = 50
h3 = x hari

p1 h1 = p2 h2 + p3 h3
100(25) = 100(15) + 50 (x)
2.500 = 1.500 + 50 x
50 x =  2.500 - 1.500
50 x  =  1000
x = 20 hari

waktu tersedia = 20 + 15 = 35 hari

12. misalkan jumlah 5 bilangan genap itu adalah
(a-4) + (a-2) + (a ) + (a + 2) + (a + 4) = 360
5a = 360
a = 72
bllangan terkcil = a - 4 = 72 -4 = 68
