Answer:
$1400
Step-by-step explanation:
Given: A ring cost $840 after a discount of 40% on the original price of the ring.
To find: Original price of the ring
Solution:
Let the original price of the ring be $x
It is given that a discount of 40% on the original price of the ring. So, we have
[tex]x-\frac{40}{100}\times x=840[/tex]
[tex]\implies x-\frac{2x}{5} =840[/tex]
[tex]\implies\frac{5x-2x}{5} =840[/tex]
[tex]\implies\frac{3x}{5} =840[/tex]
[tex]\implies x=\frac{840\times5}{3}[/tex]
[tex]\implies x=280\times5[/tex]
[tex]\implies x=1400[/tex]
Hence, the original price of the ring is $1400.
