trung bình độ tuổi mỗi cháu là:
190 :19=10 (tuổi)
trong trường hợp đen nhất mà vẫn giữ cho tuổi anna lớn nhất thì phải bớt mỗi cháu đi 1 tuổi.
vậy 18 cháu bớt 1 tuổi thì tuổi của anna là:
10+18x1=28(tuổi)
đ\s:28 tuổi

The sum of the ages of three children is 30. The oldest child is twice as old as the second oldest one. The youngest child is 10 years younger than the oldest one. Find the ages of each child.
Gọi số tuổi của 3 người lần lượt là a,b,c
Ta có: a=2b=c+10
=> b=1/2 a; c=a-10
Do đó : a+b+c=30
hay a+1/2a+a-10=30
=> a+1/2a+a=40
5/2a=40
Nên a= 16
Từ đó ta suy ra b=8 ;c=6
Vậy số tuổi của ba bạn lần lượt là 16;8 và 6
Chúc bạn làm bài tốt :)

Call three chirle is a,b,c
I have: a= 2b = c+10
=> b =\(\frac{1}{2}\) a+a=10+30
=>a+\(\frac{1}{2}a+a-10=30\)
\(=>\frac{5}{2}a=40\)
*that you have to:a=16
And three chirlen are: b= 8 c=6
a=16
That well~ :>
