Explanation

Let A be the amount of type of first rice and

B be the Amount of second type of rice

According to question:  A + B = 50 Kg

Also

                           A  x 4.5 + B x 5 = 240 Rs

Thus solving the above two equations

                    (50 – B) x 4.5 + 5B = 240

                       225 – 4.5 B + 5B = 240

                                          0.5 B = 15

                                                 B = 15/ 0.5

                                                 B = 30 Kg

                                        Thus A = 50 – 30 = 20 Kg
