Answer 1

Năm nay tuổi ông hơn số lần tuổi cháu là :

5 - 1 = 4 ( lần tuổi cháu )

Vì tuổi cháu = 1/13 tuổi ông nên tuổi ông gấp 13 lần tuổi cháu

10 năm về trước tuổi ông hơn số lần tuổi cháu là : 

13 - 1 = 12 ( lần tuổi cháu )

Hiệu số tuổi hai mỗi người không thay đổi theo thời gian

4 lần tuổi cháu hiện nay = 12 lần tuổi cháu 10 năm về trước hay :

1 lần tuổi hiện nay = 3 lần tuổi cháu 10 năm về trước 

Vậy tuổi cháu hiện nay là 3 phần , tuổi cháu 10 năm về trước là 1 phần

Ta có sơ đồ :

Tuổi cháu 10 năm về trước l---------------l

Tuổi cháu hiện nay             l---------------l----------------l----------------l

                                                                  10 năm

Tuổi cháu hiện nay là :

10 : ( 3 - 1 ) x 3 = 15 ( tuổi )

Năm sinh của chau là :

2016 - 15 = 2001

Đáp số : 2001
