Gear P makes 10 revolutions per minute, and gear Q makes 40 revolutions per minute. How many second after the gears start rotating will gear Q have made exactly 6 more revolutions than gear P?

$2500 - y scholarships$4000 - z scholarships

if total x scolarships = $37500, then$37500/1250 = 30 scolarships

x= 2* z

then z = x/2= 15 scholarships for $4000 Answer (E) Intern Joined: 08 Oct 2006 Posts: 30 Followers: 0 Kudos [?]: 5 [0], given: 0 ### Show Tags 22 Oct 2006, 02:59 Solution for the first problem: sorry answer is (A) missed one point y=2*z x=3*y=6*z if x=30, then z =5 ANSWER A is correct Intern Joined: 08 Oct 2006 Posts: 30 Followers: 0 Kudos [?]: 5 [0], given: 0 Solution for problem #2 [#permalink] ### Show Tags 22 Oct 2006, 03:20 It's impossible to solve problem #2.

V(P) = 10 rotations per minute = 10/60 rotations per second = 1/6 r per s V(Q) = 40 rotations per minute = 40/60 rotations per second = 2/3 r per s R=V*t 2/3*t - 6 = 1/6*t 4/6*t - 1/6*t = 6 1/2*t = 6 t = 12 seconds CORRECT ANSWER IS (D) SVP Joined: 05 Jul 2006 Posts: 1743 Followers: 6 Kudos [?]: 316 [0], given: 49 ### Show Tags 22 Oct 2006, 08:45 1.
