Given:
Selling price of radio for Masada = 63,000
Loss = 10%
To find:
The amount of money Masada paid for the radio?
Solution:
Let x be the amount of money Masada paid for the radio.
According to the question,
[tex]x-10\%\text{ of }x=63000[/tex]
[tex]x-\dfrac{10}{100}x=63000[/tex]
[tex]x-0.1x=63000[/tex]
[tex]0.9x=63000[/tex]
Divide both sides by 0.9.
[tex]x=\dfrac{63000}{0.9}[/tex]
[tex]x=70000[/tex]
Therefore, Masada paid 70,000 for the radio.
