Question

Que numero es ABC si 2ABC ES 17 VECES ABC

Answer 1

ABC = A(100) + B(10) + C

2000 + A(100) + B(10) + C = 17*ABC

2000 + A(100) + B(10) + C = 17*(A(100) + B(10) + C)

2000 = 17*(A(100) + B(10) + C) - (A(100) + B(10) + C)

2000 = (17 - 1) (A(100) + B(10) + C)

2000 = (16) (A(100) + B(10) + C)

2000 / 16 = A(100) + B(10) + C

125 = A(100) + B(10) + C

Entonces

A = 100
B = 20
C = 5

125 = ABC
