Vincent gives a correct answer.
It is not possible to do it without putting boxes into boxes, because the sum of 4 odd numbers is even.
My solution was: 7 balls in each of the first three boxes, then these boxes together in the fourth box.

No.
Consider 4 boxes, A, B,C, and D. If A and B both have an odd number of balls in them, the total balls in A and B together will be even. Similarly for boxes C and D. So the total of all the balls in all 4 boxes will be an even number, which means it can't be 21.

there is no way of getting a total of 21 balls in 4 boxes when the numbger of balls in each box is odd.
4 odd numbers when added up will always give an even number. so this is not possible, unless of course it is a trick question. then vincent gave the right answer.
7 in each of 3 boxes and then placing them in the fourth box.

it extremely is not plausible. permit's anticipate you need to fill the balls in this variety, and permit a(a million) be the form of balls in container a million, a(2) the form of balls in container 2 and so on. on account which you desire the form of balls in each and each container to be unusual, each and each a(n) with n between a million and one hundred may be written as a(n) = 2 x b(n) + a million the place b(n) is a organic extensive type for container n. then you certainly get one hundred = a(a million) + a(2) + ... + a(25) = (2 x b(a million) + a million) + (2 x b(2) + a million) + ... + (2 x b(25) + a million) = 2 x (b(a million) + b(2) + ... + b(25)) + 25 x a million or equivalently 75 = (one hundred - 25) = 2 x (b(a million) + b(2) + ... + b(25)) because of the fact the sum of the b(a million) + ... + b(25) is a organic extensive type, this might advise 75 is even. on account that 75 is unusual, you may not fill the packing packing containers this variety.
