A radio is being discounted 20%.if the is sale of the radio is $51.44, what was the original price of the radio?
ehidna [41]
     The Definition of Porcentage is given by:

p= \frac{V_{x}}{V_{t}}
 
     Where Vx is discounted value or increased, and Vt is total value. The discount decreases the "p" value.

p= \frac{V_{x}}{V_{t}} \\ \frac{(100-20)}{100V_{x}} = \frac{1}{V_{t}}  \\ V_{t}= \frac{51.44}{0.8}  \\ \boxed {V_{x}=64.3}

If you notice any mistake in my english, please let me know, because i am not native.

Isabel is thinking of an even number between 234 and 250 . The sum of the digits is double the digit in the ones place. What is
Dvinal [7]
Since the required number is between 234 and 250, then the first digit of the number is 2 and the second digit can either be 3 or 4.

Let the second and the third digits be x and y respectively, then

2 + x + y = 2y

Consider when the second digit is 3, then

2 + 3 + y = 2y
5 = y

Thus, the number is 235.

Similarly, consider when the second digit is 4, then

2 + 4 + y = 2y
6 = y

Thus, the number is 246.

Since the required number is an even number, therefore, Isabel's number is 246.
