A man and his daughter together weigh 90 kg, the man with his cat weigh 70 kg, and the daughter and the cat together weigh 40 kg. What do the man, the daughter and cat weigh together?

Respuesta :

I think the answer is 100kg because it could be that the dad weighs 60kg and the daughter weighs 30kg...so the cat must weigh 10kg...


60kg+30kg+10 kg=100kg
