MathProblem-Solving and Data AnalysisHard
A store raises the price of a jacket by 20%. Later, it lowers the new price by 20%. The final price is what percent of the original price?
A80%
B96%Correct
C100%The trap
D104%
Check with $100: $100→then$120→then$96
Turn each change into a multiplier.
Up 20% means × 1.20. Down 20% means × 0.80.
Apply them in order.
1.20 × 0.80 = 0.96
Read the answer.
The final price is 96% of the original. That’s B.
Why not 100%?
The 20% cut is taken from the higher price, so it removes more than the 20% increase added.

Transitions · Lesson 0
What a transition signals
A transition is a signpost. It tells the reader how the next idea connects to the one before it: does it push against it, follow from it, add to it or illustrate it?
On the SAT, all four choices fit the sentence grammatically. However, and For example, can both start a sentence. So the only question is which signpost points the right way.
Use one method every time. First, cover the choices. Read the sentence before the blank and the sentence with the blank, and more of the passage if the link reaches further back. Then name the relationship in plain words: but, so, and also, for instance, in other words, then, likewise. Only then look at the choices and pick the one that matches your word.
Naming the relationship first matters because every wrong choice is designed to sound smooth. If you try each word in the blank, several will seem fine. If you already know you need a but, usually only one choice survives.
Most transitions belong to a small number of families. Learn what each family signals, and the choices become easy to sort.
| Family | The next sentence... | Common transitions |
|---|---|---|
| Contrast | goes against or differs from the last idea | However, By contrast, In contrast, On the other hand, Nevertheless, Instead, |
| Cause and effect | is a result of, or a conclusion drawn from, the last idea | Therefore, Thus, As a result, Consequently, For this reason, |
| Addition | adds another point in the same direction | Moreover, Furthermore, In addition, Additionally, Also, |
| Example | gives a specific case of a general claim | For example, For instance, |
| Restatement | says the same idea in other words | In other words, That is, |
| Similarity | gives a second, parallel case, usually a different subject doing the same kind of thing | Similarly, Likewise, |
| Sequence | comes next in time or in a process | Next, Then, Later, Afterward, Subsequently, Finally, |
| Concession | admits a point against the writer's claim before returning to it | Granted, Admittedly, To be sure, and, when the writer returns to the claim, Still, Even so, |
| Emphasis | strengthens or sharpens the last claim | In fact, Indeed, |
Worked example Easy
For centuries, sailors crossing the open ocean found their position by measuring the angle of the Sun or a star above the horizon, using instruments such as the sextant. The method demanded skill, clear skies and careful arithmetic. most ships today find their position with satellite navigation systems, which work in any weather and require no calculations from the crew.
Which choice completes the text with the most logical transition?
- For example,
- However,Answer
- Similarly,
- In other words,
How to solve it
- Cover the choices. The earlier sentences describe the old method: angles, instruments, skill, clear skies and arithmetic.
- The sentence with the blank describes today's method, which needs none of those things. Old way versus new way: the plain word is but.
- The only contrast choice is However,.
Why each choice is right or wrong
- A. Incorrect. Satellite navigation is not a specific case of measuring the Sun or stars with a sextant. It is a different method.
- B. Correct. The sentence contrasts today's satellite method with the older method that demanded skill, clear skies and arithmetic.
- C. Incorrect. Similarly would mean satellite navigation works the same way as the sextant method, but the passage stresses that it works differently.
- D. Incorrect. In other words would introduce a rewording of the previous sentence, but the new sentence brings in a new idea: a different, modern method.
Worked example Medium
Beaver dams slow the flow of streams and spread water across the surrounding land, creating ponds and marshes where there had been only a narrow channel. stretches of stream with active beaver colonies often support a wider variety of plants, insects and birds than nearby stretches where the water runs fast and shallow.
Which choice completes the text with the most logical transition?
- In contrast,
- Nevertheless,
- Similarly,
- As a result,Answer
How to solve it
- Cover the choices. The first sentence says what dams do: they create ponds and marshes.
- The second sentence says those areas support more kinds of living things. New habitat leads to more variety, so the plain word is so.
- The comparison with nearby stretches is inside the second sentence. It is not a contrast with the first sentence, so don't let the word than pull you toward a contrast choice.
- The cause-and-effect choice is As a result,.
Why each choice is right or wrong
- A. Incorrect. The second sentence compares two kinds of stream within itself, but it does not go against the first sentence. It describes an effect of the ponds and marshes.
- B. Incorrect. Nevertheless means "despite that," but greater variety is not something that happens in spite of the new ponds and marshes. It happens because of them.
- C. Incorrect. Similarly would introduce a parallel case, something doing the same thing as beaver dams. The second sentence describes the effect of the dams themselves.
- D. Correct. The ponds and marshes that dams create lead to the wider variety of plants, insects and birds, so the second sentence is a result of the first.
