Rice 1 125 kg, soybean 1875 kg.

Ok, total weight = weight of each bag * number of bags.

It is known that the weight of each bag of rice is three times that of each bag of soybeans, and the number of bags of soybeans is five times that of rice.

In units of soybeans.

Rice =3* 1/5=3/5

Add up to 3/5+ 1=8/5.

Soybean accounts for 5/8 and rice accounts for 3/8.

3000*5/8= 1875

3000*3/8= 1 125
