Jenny = 228 + Jack

Also Jenny+133 = 2(133+Jack)

228+Jack+133 = 266 + 2Jack
Jack = 95

Then Jenny = 228+95 = 323.

D is the answer.

Let
No.of marbles John have = x
No.of marbles Jenny have = x+228

Bob gave 133 each to Jack (Jk) and Jenny(Jn).

No.of marbles(JK)= x+133
No.of marbles(Jn)= x+228+133=x+361

No.of marbles Jn= 2*(No.of marbles JK)

X+361=2*(x+133)
X+361=2x+266

Solving eqtn
2x-x=361-266

X=95= No.of marbles Jack

No.of marbles Jenny=95+228 =323

ANWSER- Opt - D

Jenny has 228 more marbles than Jack, so option A and B are out.

Between C, D and E, only 323 is odd and adding 133 to it can give an even number which can be twice of an integer value, so C and E are out as well.

Hence, answer is D.

Jenny = a and Jack= b

a=b+228== (1)

a+133= 2(b+133)-- (2)

solve for a & b using 1 & 2

we get a as 323 and b as 95

IMO D Bunuel answer should be option D not E..

"Jenny has 228 more marbles...How many marbles does Jenny have now?" Well, A and B are out!!
We are left with C, D, and E. Let's just try D. If we need something smaller, it's C; if larger, E.
Jenny has 323. Jack has 95. 323+133=456. 95+133=228. Is 456 twice as many as 228? Yep.

Answer choice D.

228+133= 361, Im not sure if the wording is off here or I have missed something terribly obvious, but Jenny must have at least 361 marbles before even factoring in bob, so how is the answer 323? I am baffled.

But it is stated Jenny has 228, then they both receive 133 from bob therefore before even considering jack, Jenny alone must have 361+ marbles, thus it cannot be d no?

The wording is perhaps not perfect, but let's review the question, which is the following:

How many marbles does Jenny have now?

Now, let's review the information given:

If Bob gives each of them 133 marbles, Jenny will have twice as many marbles as Jack.

We see that the question is about "now" whereas the information about Bob giving them 133 marbles is about what possibly "will" occur in the future.

So, the number referred to by the question about the marbles Jenny has "now" does not include the 133 from Bob.

Thus, it's not true that "now" Jenny must have at least 228 + 133. Rather, she must have at least 228.
