    • k % 3 = 1
    • k % 4 = 1
    • k % 5 = 1
    • k % 6 = 1
    • k % 7 = 1
    • k % 8 = 1
  • Ta thử lần lượt với các giá trị k tăng dần:

    • k = 1: Không thỏa mãn điều kiện.
    • k = 2: Không thỏa mãn điều kiện.
    • k = 3: Thỏa mãn điều kiện (vì 3 % 3 = 03 % 4 = 33 % 5 = 33 % 6 = 33 % 7 = 33 % 8 = 3).
    • Vậy n = 3 là một giá trị thỏa mãn.

Tóm lại, trong hộp có ít nhất 3 quả bóng bàn thỏa mãn yêu cầu của bài toán.

A favourite pastime with children and adults alike is betting on cricket fights during the rainy season. Children catch crickets and sell them for this purpose.

Horse racing held on Saturday and Sunday in a Saigon suburb draws large crowds as thousands of Vietnamese, young and old, turn out to cheer the pint-sized Asiatic horses and jockeys on to victory. Betting is heavy, with profits going into the national treasury of Southern Vietnam. It is not uncommon to see a horse run the wrong way around the track.

Other popular sporting events include soccer, basketball, volleyball, swimming, hiking, ping pong, and tennis. Vietnam teams often compete with other countries in soccer, tennis, bicycling, basketball, and other sports.

There are few golf courses in Southern Vietnam. The one in Saigon is located near Tan Son Nhat Airport. It may well be the only golf course in the world fortified by pillbox installations on its perimeter, with soldiers and machine guns inside. There is an excellent golf course in Da lat. Caddies are usually women.

A. Yes, there are no golf course.

B. Yes, there are few.
