Xếp thành hàng 12, 15, 18 hàng đều thừa 5 hs
=> x‐5 thuộc BC ﴾12; 15; 18﴿ và 200<x‐5<400
BCNN ﴾12; 15; 18﴿
12= 222.3
15= 3.5
18= 2.322
BCNN (12; 15; 18) = 222.322.5 = 4.9.5 = 180
BC (12; 15; 18)= B(180) = {0;180;360;540;......}
mà 200<x‐5<400
nên x‐5=360
x= 360+5= 365
vậy số học sinh khối 6 đó là 365 hs
TL
Ta có :
BCNN (12,15,18)=180
Vậy số học sinh khi bớt đi 1 là một bội của 180, do đó bằng 180 k với k là một số tự nhiên.
Theo đề bài ta có
200<180 k<400
<=>1<k≤2
Vậy k=2 và số học sinh của trường khi bớt đi 1 là 180.2=360
Vậy số học sinh của trường đó là :
360+1=361 (học sinh)
Đs : 361 học sinh
