2740-x=C..............(1)

3650+x=M............(2)

M=4C..................(3)

we have 3 equations and 3 variables, we can solve for each.

Add  (1) and (2)

2740-x+3650+x=C+M

6390=C+M............(4)

Substitute C=M/4 from equation (3) into (4)

6390=5M/4

M=5112

Plug into (3)=> 5112=4C =>  C=1278

Plug C and M into (1)

2740-x=1278

x=1462.

Thus, Minmin ended with 5112 rice. Chicqui ended with 1278 rice. Chiqui gave 1462 rice to Minmin. The answer to your one question is, Minmin had 5112 sacks of rice in the end.
