Vì mẹ sinh con lúc 26 tuổi nên mẹ hơn con 26 tuổi
Ta có tuổi mẹ và tuổi Minh = 48 tuổi
Khi đó tuổi của Minh là :
( 48 - 26 ) : 2 = 11 ( tuổi )
Do đó năm 2012 thì Minh 11 tuổi
=> Sinh năm : 2012 - 11 = 2001
Vậy minh sinh năm 2001
p/s : k mik nhs : Pé Mon
gọi tuổi của Tâm năm 2019 là x
khi đó tuổi của mẹ Tâm là x+26
tổng tuổi của hai mẹ con là : \(x+26+x=2x+26=42\text{ nên }x=8\)
vậy năm 2019 thì Tâm 8 tuổi hay Tâm sinh ra năm 2011
ta thấy tuoi minh thua tuoi me 26 tuoi
tuoi minh la
(48-26)/2=11 tuoi
tuoi me la
11+26=37
Me sinh thach luc 26 tuoi nghia la me hon thach 26 tuoi
nam 2005, tuoi thach la: (42-26): 2=8 tuoi
thach sinh vao nam: 2005-8= 1997
Ds:nam 1997
