With much success from writing the 10 Harry Potter books,

The final fight is between B & E becasue rest of them have modifier issue.
B -> correct idiom - estimated to be...
E -> has had - incorrectly used.

Cheers!

With much success from writing the 10 Harry Potter books, J.K. Rowling's sales have made her worth over $1 Billion.

The first part of the sentence is refered to the author, so the author must follow in the next part.

A)J.K. Rowling's sales have made her worth over $1 Billion
Here the subject are the sales, not the author
B)J.K. Rowling is estimated to be worth over $1 Billion
CORRECT
C)J.K. Rowling's sales have made her worth more than $1 Billion
Here the subject are the sales, not the author
D)J.K. Rowling's net worth is estimated to be over $1 Billion
Here the subject is the net worth, not the author
E)J.K. Rowling has had income worth over $1 Billion
This is just awkward, and changes the meaning of the sentence. All the other answers talk about her worth now, this one says that she once had such an income.

With much success from writing the 10 Harry Potter books, J.K. Rowling's sales have made her worth over $1 Billion.

Who has got much success from writing 10 HP books? JK rowling or JK rowling sales?
It is J K Rowling boz the initial modifier , needs to be closest to the subject it modifies and that is JK Rolwing

How can we estimate worth of a person ?
We can estimate worth of her assets.
Can we say
what is the worth of Mr.xyz ?
or
what is the worth of Mr.xyz's assets ?

Hi all,
this question seems to be awkwardly constructed from the very word go..
the underlined portion is straightway questionable in which a person is estimated to be worth something..
even the non underlined portion does not make sense in its construction
"With much success from writing the 10 Harry Potter books"
achieving much success from writing of the 10 Harry Potter books.. is the best it can come to and it will still be wrongly worded..
Regards

Hi chetan2u

Can't agree more with you. The sentence seems a nuisance from the very start. W/o fluff B stands: With success, J.K. Rowling is estimated to be worth over $1 Billion.
I think this is not a great construction. A Verb+ing or a Verb+ed modifier could have done the job better than the prepositional phrase: With much success.
Experts pls comment on the matter.
Thanks.

Hi expert,
I opt for option D with the following 2 reasons.

1)IMO,a person can't be worth.
Can we quantify person as in the correct choice?
Given that Joe has his asset worth $5 billion,we can say Joe worth $5 billion?

2)In option E,the use of present perfect is not to point out a particular event occurs before the other,but to indicate that this event started in the unspecified time in the past.
Is my understanding incorrect?

The problem with option D is that "With much success from writing the 10 Harry Potter books" should refer to J.K.Rowling, not his net worth. Option B is the best of the lot - though it should be clear that a person's work is worth some value, in absence of other grammatically correct sentence, it is acceptable to state that the person himself is worth some value (because of his work).

In option E the verb "to have" is used in present perfect. The meaning implied is that JKR had income worth over $1 Billion at some point of time in the past, and the effect of having that income is still there - this meaning is not intended.

If the intended meaning were that JKR had income at some point in the past, simple past tense would be appropriate.

why is D wrong?
though i agree B is correct but what is wrong with D?

Simply because D says that Rowling's net worth has had much success from writing the 10 HP books and not Rowling .

1. J.K. Rowling has success, not her sales ---> A, C, D are out.
2. It is logical that we talk about now, not about some time in past ---> E is out.
3. So it is B (plus for us: estimated to be - nice correct idiom)
