First of all, the interview dress is determined by the nature of the job-seeking industry. If the workers in the job-seeking industry wear casual clothes, you can wear casual clothes, but the casual clothes for the interview should not be too casual, such as slippers or too revealing, such as IT.

However, for the staff of the top 5 enterprises, our impression of this kind of industry is formal, so it is better to wear formal clothes for interviews. In addition, it is cold in winter, so you can dress up and put on a coat.

The answer is that the person at the front heard the two people at the back say "I don't know". He assumed that he was wearing a white hat, so the person in the middle saw the white hat he was wearing. Then

first, divide 9 grams of rice in half (put them at both ends of the balance respectively), that is, 45 grams on each side of the balance;

Take 45 grams of rice and weigh two 225 grams of rice in the same way;

Finally, put a 5-gram and a 2-gram weight on one side of the balance, and put some of the previously weighed 225 grams of rice on the other side to keep the balance. The rice on the balance is 25 grams, and 25 grams are taken out of the previously weighed 225 grams of rice, so the rest is 2 grams of rice;

ok, now you can send this 2 grams of rice to her mother!
