Answer 1

1. Proportion:

3500 – 100 %

x – 20 %

$x = \frac{3500 \times 20}{100}=700$

New price = 3500 -700=2800

2. 100%-10%=90%

Proportion:

90% - 3600

100% - x

$x= \frac{100 \times 3600}{90}= 4000$

3. Proportion:

100 %-60%=40%

500000 – 100%

x – 40 %

$x = \frac{500000 \times 40 }{100}=200000$
