Question

Daca 180-{4×[28-(30+m):8]-8}=120, atunci produsul cifrelor lui m este: .........

Answer 1

180-{4×[28-(30+m):8]-8}=120
4×[28-(30+m):8]-8=180-120
4×[28-(30+m):8]-8=60
4×[28-(30+m):8]=60+8
4×[28-(30+m):8]=68
28-(30+m):8=68:4
28-(30+m):8=17
(30+m):8=28-17
(30+m):8=11
30+m=11×8
30+m=88
m=88-30
m=58
produsul lui m=5×8=40
