You *may find out the box soon if you are lucky. You
may
think
you
will
have to use the scale ten times if the eleven-gram balls are in the last box.
But listen. There is a way to find out the box with eleven-gram balls by
using the scale ( ② ). Do you know the way? I'll tell you.
First, take a ball or balls out of each box. When you do so, one thing is
very important. The *number of the balls and the box number must be the
same. For example, you must take one ball out of the No. 1 box, two balls
out of the No.2 box, and ( ③ ) balls out of the No. 10 box. If you do r
so, you will have ( ④ ) balls. Next, put all the balls on the scale.
Remember all the balls in one box are eleven grams. If the scale shows 553
grams, what does it mean? It means three balls on the scale are eleven grams.

box. If the scale shows ( ⑦ ) grams, it means all the balls in the No. 6
box are eleven grams. And if the ( ® ) box has eleven-gram balls, the
Scale will show 558 grams.
Logical thought is important for you. It is useful to *solve the problem
more easily.
