Take Q 90+30
120/300
40%

9000×65% + 9000×112% = 15930
10800×60% + 10800×112.5% = 18630

Total = 34560

Sold = 3465 + 5184

Unsold = 34560 - 8649 = 25911

36 : 9
+4 : +3
40 : 12 =
water : milk = 3:10

14+16)2= 15
12+8= 20

1500/20= 75%

Solution

x + y + z = 16× 3 = 48
z - x = 12
z - y = 3 ( y - x) = 3y - 3x
12 + x + 3x = 4y
y - x = 3 , y + 12 - z = 3 => y = z - 9

z - 12 + z - 9 + z = 48
z = 23
