Answer 1

Answer:

47 Ducks and  7 piglets.

Step-by-step explanation:

Lets try 27 of each to start

Ducks Piglets  Total legs

27        27          54 + 108 = 162.  Too many

30        24          60 + 96  =  156   Too many. Increase the ducks by 10:

40        14           80 + 56  =   136.  

50          4          100 + 16  = 116 This < 122 so ducks between 40 and 50..

45           9          90 + 36 = 126  Too high so increase  ducks:

46           8          92 + 32 = 124  Close.

47           7           94 + 28 = 122.
