2 boxes of s.berry and 3 boxes of milk to each students...
24 boxes per carton...

a)  \frac{234}{3}
  
 = 78 boxes of milk
 = (24 x 3 = 72) ~~ (24 x 4 = 96)
 soo
 = 4 cartons of milk that needs to buy..

b) 96 - 78
  = 18 boxes of milk
kenapa divide 3 ?
untuk tahu berapa jumlah kotak susu yg diperlukan
234 tidak divide 2 kenapa?
sebab.. soalan minta jumlah kotak susu yg diperlukan... bukan jumlah kotak strawberry yg diperlukan :))

234 pupils
2s + 3c

a) 1 carton = 24 boxes

234 (2s +3c)
= 468s + 702c

468s /24 = 19.5 = 20s
702c /24 = 29.25 = 30c

therefore, 20 cartons of strawberry and 30 cartons of chocolate fresh milk flavours are needed

b) remaining boxes after distribution

strawberry flavour
= 20(24) - 468
= 480 - 468
= 12 boxes

chocolate flavour
= 30(24) - 702
= 720 - 702
= 18 boxes

therefore, the remaining are 12 boxes of strawberry and 18 boxes of chocolate fresh milk flavours.
