Answer 2

erau meri peri nuci  hai sa-i notam cu m. p. n.                                          
n+p=1040                                                                                                  
n+p+m=2130                                            meri=1090                                                    
m=2130-1040                                        nuci=500
m=1090                                                 peri=540
m=n+590
n=1090-590
n=500
n+p=1040
p=1040-500
p=540
