It is three star question to check your answer..

Good try, you must have already figured it out- this answer is not correct.

8x 21 = 3 x56
8+21 = 29, which is a qualified sum; (see my another post below).
3+56 = 59, which is also a qualified sum;

Thus, P can eliminate 4& 42, 6 &28, 12 &14,
but he can never figure out if it is 8&21 or 3 &56.

So, this answer is incorrect.
