Question

se da numarul natural n astfel incat 100<n<500.Sa se afle n stiind ca impartit la 5 da restul 1,impartit la 10 da restul 6 si impartit la 13 da restul 9.Va rog urgent

Answer 1

n=5xc1+1=10xc2+6=13xc3+9

n+4=5(c1+1)=10(c2+1)=13(c3+1)

n+4= M [5,10,13]

n+4={130, 2x130, 3x130}; n+4={130,260,390}

n={126, 256, 386}
