If every box contained 11 balls that would account for only 99 balls. The hundredth ball has to be placed in a box already containing 11 balls...

How do you divide 27 tennis balls into 3 groups so the ratio is 2 to 3 to 4?
The groups have 6, 9 and 12 tennis balls Consider how many parts there are: in ratio of 2 : 3 : 4 there are 2 + 3 + 4 = 9 parts. With 27 tennis balls, each part is worth 27 ÷ 9 = 3 tennis balls. Thus, in the first group there are 2 parts = 2 x 3 = 6 tennis balls, in the second group there are 3 parts = 3 x 3 = 9 tennis balls, and in the third group there are 4 parts = 4 x 3 = 12 tennis balls. To check: 6 + 9 + 12 = 27
Out of 9 balls 8 balls weight the same 1 is lighter. using scales twice which ball is lighter?
Set three balls aside. Divide the remaining 6 balls into 2 groups of 3 and weigh them. If the groups weigh the same, the lightest ball must be in the group you set aside. Otherwise, the lightest ball is in the group that weighed less. Take the group of thee that remains and set aside one ball. Weigh the other two. If the two balls weigh the same, the lightest ball must be the one you set aside. Otherwise, the lightest ball is the one that weighed less.
