As advertised on the main page of Beat the GMAT, Brian, David and I will be posting some original questions today and tomorrow with prizes for the first five correct responders who show their work!
Good Luck!

Let p = the product of all the odd integers between 500 and 598, and let q = the product of all the odd integers between 500 and 602. In terms of q, what is the value of 1/p + 1/q ?
(A) 1/(600q)
(B) 1/(359,999q)
(C) 1,200/q
(D) 360,000/q
(E) 359,999q
Answer: D 360,000/q
q=p*599*601= 359999p
therefore, p=q/359,999
1/p + 1/q = 1/(q/359,999) + 1/q
= 359,999/q +1/q = 360,000/q
(A) 1/(600q)
(B) 1/(359,999q)
(C) 1,200/q
(D) 360,000/q
(E) 359,999q
Answer: D 360,000/q
q=p*599*601= 359999p
therefore, p=q/359,999
1/p + 1/q = 1/(q/359,999) + 1/q
= 359,999/q +1/q = 360,000/q

p = 501*503*..........597
q = 501*503*..........597*599*601
hence,
q = p * 599*601
p = q/(599*601)
1/p + 1/p = (599*601)/q + 1/q =
360000/q
Ans: D
q = 501*503*..........597*599*601
hence,
q = p * 599*601
p = q/(599*601)
1/p + 1/p = (599*601)/q + 1/q =
360000/q
Ans: D

p= 501x503...x597
q=501x503....x599x601
p =q/(599x601)
1/p +1/q = [(599x601)+1]/q = 360000/q
D is correct.
q=501x503....x599x601
p =q/(599x601)
1/p +1/q = [(599x601)+1]/q = 360000/q
D is correct.
Dear life , When I said "Can my day get any worse" It was a rhetorical question not a challenge!
Answer: (D)
Let p = the product of all the odd integers between 500 and 598, and let q = the product of all the odd integers between 500 and 602. In terms of q, what is the value of 1/p + 1/q ?
(A) 1/(600q)
(B) 1/(359,999q)
(C) 1,200/q
(D) 360,000/q
(E) 359,999q
Solution:
p=501*502*503*..... ...*597
q=501*502*503*..... ...*597*599*601
--> q=p*599*601
--> p=q/(599*601)
(1/p) + (1/q)= (599*601)/q + 1/q
= (359999 + 1)/q
= 360,000/q -- Answer(D)
Let p = the product of all the odd integers between 500 and 598, and let q = the product of all the odd integers between 500 and 602. In terms of q, what is the value of 1/p + 1/q ?
(A) 1/(600q)
(B) 1/(359,999q)
(C) 1,200/q
(D) 360,000/q
(E) 359,999q
Solution:
p=501*502*503*..... ...*597
q=501*502*503*..... ...*597*599*601
--> q=p*599*601
--> p=q/(599*601)
(1/p) + (1/q)= (599*601)/q + 1/q
= (359999 + 1)/q
= 360,000/q -- Answer(D)

Solution:
Since, p=501*503*505*....*597 (product of all odd integers between 500 and 598)
and q=501*503*505*.....*597*599*601 (product of all odd integers between 500 and 602),
We may re-write q= p*599*601
or,q= p*359999
or,p= q/359999
Hence, 1/p + 1/q= 359999/q + 1/q
= (359999+1)/q
= 360,000/q
Choose (D).

= (359999+1)/q
= 360,000/q
Choose (D).
