Anna is 10 year old

8 tháng 3 2017

mình chả hiểu j cả

is that true ? I don't think Donald Trump has 19 grandchildren. How many children does Trump have ? after that I will answer your question !

7 tháng 3 2017

At least Anna must be 10 years old

30 tháng 3 2018

Donald Trump có 19 cháu, tất cả các lứa tuổi khác nhau. Anna là người lớn tuổi nhất. Tổng số tuổi của lứa tuổi của tất cả các cháu là 190.Am là bao nhiêu tuổi Anna?

30 tháng 3 2018

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
