Explanation:
Please find the complete question in the attachment.
In point 1:
The answer is =70.000
In point 2:
[tex]=70.000+28.000 \times 25\%\\\\=70.000+28.000 \times \frac{25}{100}\\\\=70.000+28.000 \times \frac{1}{4}\\\\=70.000+ 7 \\\\=77.000\\\\=77[/tex]
In point 3:
[tex]=70.000+(1-(1-25 \%) \times \frac{(1-10\%)}{(1-26\%)) \times 28.000}\\\\=70.000+(1-(1- \frac{25}{100}) \times \frac{(1- \frac{10}{100})}{(1-\frac{26}{100})) \times 28.000}\\\\=70.000+(1-1+ \frac{1}{4}) \times \frac{(\frac{ 10-1}{10})}{( \frac{100-26}{100})) \times 28.000}\\\\=70.000+(\frac{1}{4}) \times \frac{(\frac{9}{10})}{(\frac{74}{100})) \times 28.000}\\\\=70.000+(\frac{1}{4}) \times \frac{0.9}{20.72}\\\\=70.000+ \frac{0.9}{82.88}\\\\=70.000+0.01058\\\\=70.01058\\\\[/tex]
