Answer 1

Answer:

Step-by-step explanation:7 bags of rice and 4 carontons of milk weight 15kg and 2 bag 2 carton 4.8 kg

If we double the second we get

4 bag 4 carton=9.6 kg

And subtract the second from the first we get 3 bags =5.4 kg

So 1 bags weight=1.8kg

And subtract 4 bags weight from second we get 9.6-7.2=2.4kg

4carton=2.4kg

1 carton=0.6kg
