Gọi : a là thừa số thứ nhất
Gọi : b là thừa số thứ hai
_Nếu tăng thừa số thứ nhất thêm 3 đơn vị,giữ nguyên thừa số thứ hai thì tích tăng thêm 21 đơn vị , nên ta có phương trình
( a + 3 ) x b = ab + 21
<=> ab + 3b = ab + 21
<=> 3b = 21
<=> b = 7 ( 1 )
Vay : THỪA SỐ THỨ HAI LÀ 7
_Nếu tăng thừa số thứ hai thêm 5 đơn vị,giữ nguyên thừa số thứ nhất thì tích tăng thêm 240 đơn vị , nên ta có phương trình :
( b + 5 ) x a = ab + 240
<=> ab + 5a = ab + 240
<=> 5a = 240
<=> a = 48 ( b )
Vay : THUA SO THU NHAT LA 48
H CUA HAI THUA SO LUC DAU LA :
7 x 48 = 336
dap so : 336
