Cái từ "dights" có vẻ như nên thay bằng "digits"

Có thể dùng phương pháp loại trừ

Nếu đáp án A đúng thì số 1 đã được đặt đúng vị trí (trái với dữ kiện đầu tiên)

Nếu đáp án B đúng thì có nghĩa chỉ có số 4 được đặt đúng vị trí (trái với điều kiện thứ hai)

Nếu đáp án D đúng thì có nghĩa chỉ có số 4 được đặt đúng vị trí (trái với điều kiện thứ hai)

Như vậy chỉ có đáp án C đúng. Hai số được đặt đúng vị trí là $3$ và $2$. Hai cặp số đúng là $41$ và $32$

Gọi S là quãng đường
v là vận tốc

t là thời gian Mr.J đi thường ngày

=>\(\dfrac{S}{120\%v}=t-1\)

\(\dfrac{100}{v}+\dfrac{S-100}{130\%v}=t-1\)

=>\(\dfrac{S}{120\%v}=\dfrac{100}{v}+\dfrac{S-100}{130\%v}\)

<=>\(\dfrac{130S}{156v}=\dfrac{15600+120S-12000}{156v}\)

<=>\(10S=3600\)

<=>\(S=360\)
