Answer 1

Respuesta:

29

Explicación paso a paso:

Hallar A-B

Calcular:

$a = 600 \times \frac{15}{100} \times \frac{30}{100} \\ a = 6 \times 15 \times \frac{3}{10} \\ a = \frac{270}{10} \\ a = 27$

$b = 800 \times \frac{20}{100} \times \frac{35}{100} \\ b = 8 \times 2 \times \frac{35}{10} \\ b = 16 \times \frac{35}{10} \\ b = \frac{560}{10} \\ b = 56$

Hallar B-A

B=56

A=27

56-27=29
