Respuesta:

dieciséis

Explicación paso a paso:

100-ab - - - - (1)

100-ba - - - - (2)

Sumando (1) y (2) sumas hasta 24

100-ab + 100-ba = 24

100 + 100 - ab - ba = 24

200- (10a + b) - (10b + a) = 24

200-10a-b-10b-a = 24

200-24 = 10a + 10b + b + a

176 = 11a + 11b

176 = 11 (a + b)

176/11 = a + b

16 = (a + b)
