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

Answer:

Amount gained = $900

Step-by-step explanation:

Let the cost price be = x

Given selling price = 8400

And profit% = 12%

Profit = selling price - cost price

        = 8400 - x

Profit \ \% = \frac{profit}{cost \ price} \times 100\\\\12\% = \frac{8400 - x}{x} \times 100\\\\\ 12 \times \frac{1}{100} = \frac{8400 - x}{x}\\\\\frac{12 \ x}{100} = 8400 - x \\\\\frac{12x}{100} + x = 8400\\\\12x + 100x = 8400 \times 100\\\\112x = 8400 \times 100\\\\x = \frac{8400 \times 100}{112} = 7500

Therefore , cost price of the radio $7500

The amount she gained = 8400 - 7500 = $ 900

Solve the following equation for the variable indicated<br> 15 = Зn + 6р, for n
Taya2010 [7]

Answer:

Solving the equation 15 = 3n + 6p for variable n we get \mathbf{n=5-2p}

Step-by-step explanation:

We need to solve the equation 15 = 3n + 6p for variable n

Solving:

15 = 3n + 6p

Subtract both sides by 6p

15-6p = 3n +6p -6p\\15-6p=3n

Switch sides of equality

3n=15-6p

Divide both sides by 3

\frac{3n}{3} =\frac{15-6p}{3}\\n=\frac{3(5-2p)}{3}\\n=5-2p

So, solving the equation 15 = 3n + 6p for variable n we get \mathbf{n=5-2p}

You jog 2 kilometers in 12 minutes. At this rate, it will take______ minutes to finish a 5k race.
mel-nik [20]
I hope you want the time taken to finish a 5 km race. Based on this i am solving the problem given.
Amount of time required to jog 2 kilometers = 12 minutes
Then
Amount of time required to jog 1 kilometer = (12/2) minutes
                                                                     = 6 minutes
So
Amount of time required to jog 5 kilometers = (6 * 5) minutes
                                                                       = 30 minutes
So it will take 30 minutes to finish a 5 kilometer race. I hope the procedure is clear to you.
