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.

Form, Structure, and Sense · Lesson 1
Pronoun–antecedent agreement
A pronoun stands in for a noun, called its antecedent. The pronoun must match that noun in number. A singular thing takes it and its; a plural noun takes they, them and their.
To solve a pronoun question, ask what the blank refers to, then find that noun in the passage. As with verbs, the closest noun is often a decoy. In the museum rotates the paintings in collection, the collection belongs to the museum, so the answer is its, not their.
A noun that names a single organization or group, such as museum, agency, company or committee, is singular on the SAT. It takes it and its, even though it is made of many people.
Pronouns also have case. Subject pronouns (I, he, she, we, they) serve as the subject of a verb; object pronouns (me, him, her, us, them) serve as the object of a verb or follow a preposition. When a pronoun is paired with another person, drop the other person and read the sentence: the judges asked Priya and me becomes the judges asked me.
Worked example Easy
Each spring, the city's art museum rotates about a third of the paintings in permanent collection, so regular visitors often find works they have never seen before.
Which choice completes the text so that it conforms to the conventions of Standard English?
- their
- it's
- they're
- itsAnswer
How to solve it
- Ask whose permanent collection it is. It belongs to the museum, not to the paintings.
- The city's art museum is singular, so the pronoun must be singular and possessive.
- Its is the singular possessive pronoun.
Why each choice is right or wrong
- A. Incorrect. Their is plural. It matches the nearby noun paintings, but the collection belongs to the singular museum.
- B. Incorrect. It's is a contraction of it is, and it is permanent collection makes no sense.
- C. Incorrect. They're is a contraction of they are, and it is also plural.
- D. Correct. Its is the singular possessive pronoun, and it refers to the museum that owns the collection.
Worked example Medium
Female sea turtles spend nearly their entire lives at sea but must come ashore to lay eggs. Many of them return to nest on the same stretch of coast where hatched decades earlier.
Which choice completes the text so that it conforms to the conventions of Standard English?
- it
- she
- theyAnswer
- one
How to solve it
- Ask who hatched on that coast. The turtles who are returning to nest did.
- In this sentence those turtles are Many of them, which is plural.
- The pronoun must be plural, and it is the subject of hatched, so it must be the subject form: they.
Why each choice is right or wrong
- A. Incorrect. It is singular, but the pronoun refers to Many of them, the plural group of female sea turtles.
- B. Incorrect. She would fit a single turtle, but the sentence is about Many of them, which is plural.
- C. Correct. They is plural and refers to Many of them, the female sea turtles that return to nest.
- D. Incorrect. One is singular and has no antecedent here. The pronoun must refer back to Many of them.
