### The cost of a bike is listed at 30% off the marked price. If the marked price is $2000, then find the cost price.

The original selling price is $2000. And the new selling price is 30% off. It means the markdown percentage is 30%.

When there is decrease is value it's the case of markdown percentage.

Let's see the formula for markdown percentage

Incase of a markdown, there is decrease in percentage of selling price.

For the above formula, we have all values except for the cost price. So we will rearrange the formula to get the cost price. To rearrange the above forumula, we will multiply L.H.S and R.H.S of the above equation by selling price. And we will divide both the sides by 100. Then we get the formula as follows:

We will substitute the respective values.

600 = 2000 - cost price

Rearranging the above equation, we get

Cost price = 2000-600

Cost price = 1400

So the cost price of the bike is $1400.

Therefore option (d), which is '$1400' is the right option.

### A sportsman increased his target of daily jog of 15 miles by 22%. His new target will be ________ miles.

The original value of the daily jog is 15 miles. And the mark-up percentage on the original value is 22%.

We have to find the new of the daily jog of the sportsman. Considering the given data, it can be done using the formula for mark-up percentage.

The formula for mark-up percentage is as follows:

We can see we have all the values from the given formula except the new value. So what we will do is rearrange this formula in a way to find the new value.

So to rearrange, first we will multiply both sides by original value and divide both sides by 100. On the right side of the equation, we are left with only the new value minus the original value. The equation becomes as follows:

.

3.3 = new value - 15

Rearranging the above equation we get,

New value = 15+3.3

=18.3

Therefore the new value of daily jog is 18.3 miles.

So option (b), which is '18.3' is the right answer.

### The capacity of a container was increased from 35 gallons to 50 gallons. Determine the percent mark-up.

For this question, the original capacity is 35 gallons and the new capacity is 50 gallons.

Now we have to find the mark-up or increase in the original value. The formula for mark-up is as follows:

Mark-up = new capacity - original capacity

= 50 – 35

=15

So the increase in capacity is 15 gallons

Let’s find the percentage mark-up. It means a percentage increase in the original value. In this case, the percentage increase in the capacity of gallons is the mark-up percentage.

The formula for mark-up percentage is as follows:

For this case we can write,

Now we will substitute all the values.

= × 100

= 0.4285 × 100

= 42.85%.

So we can see that the percent mark-up in the capacity of the gallon is 42.85%.

Therefore, option (a), which is '42.85%' is the right option.

Now we have to find the mark-up or increase in the original value. The formula for mark-up is as follows:

Mark-up = new capacity - original capacity
