Weighing the baby at the clinic was a problem. The baby would not keep still and caused the scales to wobble. So I held the baby and stood on the scales while the nurse read off 78kg.
Then the nurse held the baby while I read off 69kg. Finally I held the nurse while the baby read off 137kg.
What was the combined weight of all three?
