By selling a radio for $8400 a dealer gained 12% .how much money did she gain​
Mkey [24]

See, in these type of questions always first assume your original price to be x. And now try to write whatever information is given to you.

Now, you have that it has been sold for 12% profit, so basically it is sold at. (1 + (12/100))x = 1.12x

Now it is given that if it had been sold for 33₹ more. I.e. if it had been sold at. 1.12x + 33

Net gain would have been 14%.

So gain of 14%, means the cost to be (1+(14/100))x = 1.14x

And basically both 1.12x +33 and 1.14x are final costs, so

1.14x = 1.12x + 3

=> 1.14x - 1.12x = 3

=> 0.02x = 3

=> x = 3÷0.02

=> x= 1650₹

So original cost is 1650₹.

Hope you understand the solution and the way to tackle these type of problems if not then let me know.

hope it helps

pls mark my anwers as brainiest

Percents
Yuki888 [10]

Answer:

Percentage: 115%

Decimal: 1.15

Fraction: \frac{23}{20}\\

Step-by-step explanation:

<u>Percentages, Fractions, and Decimals</u>

Assume we set 100% as the original price of the food that Michael consumed. When he leaves a 15% tip for the waitress, he is really paying 100%+15%=115% of the original price.

Now we express 115% as a decimal, simply dividing by 100:

115% = 115/100 = 1.15

To express it as a fraction, we simplify the division instead of calculating it:

115% = \frac{115}{100}

Simplifying by 5:

115% = \frac{23}{20}
