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.

D. 323

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..
