Question

A= 20% más del 20% menos de 800
B= 100% más del 99% menos de 1000
Calcular :(A + B)

Answer 1

Respuesta:

(A + B) = 788

Explicación paso a paso:

A = (100% + 20%)(100% - 20%)(800)

A = (120%)(80%)(800)

A = (120 / 100)(80 / 100)(800)

A = (12)(8)(8)

A = 96(8)

A = 768

B = (100% + 100%)(100% - 99%)(1000)

B = (200%)(1%)(1000)

B = (200 / 100)(1 / 100)(1000)

B = (2)(1)(10)

B = 20

(A + B) = (768 + 20)

(A + B) = 788
