5 sekolah = 1800
s = 750
P = 30%
T = 20%
R = 60%
Q = x

a)
1800 - 750 = 1050
P = 30% x 1800 = 540

b)
R = 60% x 1800
    = 1080

R - S = 1080 - 750
         = 330

c)
T = 20% x 1800 = 360
                           = 360/1800 x 360
                           = 72
P = 540/1800 x 360 
   = 108

R = 1080/1800 x 360
    = 216

S = 750/1800 x 360
   = 150

x + 72 + 108 + 216 + 150 = 360
x = - 186
