A train can travel 50% faster than a car. Both start from point A at the same time and reach point B at 75 kms away from A at the same time. On the way, however, the train lost about 12.5 minutes while stopping at the stations. The speed of the car is?
[ "145 km/hr", "151 km/hr", "110 km/hr", "120 km/hr" ]
D
E Let speed of the car be x km/hr. Then, speed of the train = 150/100 x = 3/2 x km/hr. 75/x - 75/(3/2 x) = 125/(10 * 60) 75/x - 50/x = 5/24 = 120 km/hr.

What produces the centripetal force to keep the earth orbiting the sun?
[ "heat", "weight", "gravity", "motion" ]
C
Centripetal force is, simply, the force that causes centripetal acceleration. Objects that move in uniform circular motion all have an acceleration toward the center of the circle and therefore, they must also suffer a force toward the center of the circle. That force is the centripetal force. For orbiting satellites, ...

If xerox paper costs 5 cents a sheet and a buyer gets 10% discount on all xerox paper one buys after the first 2000 papers and 20% discount after first 10000 papers, how much will it cost to buy 25000 sheets of xerox paper?

C
For first 2000 pages - cost 5 cents/paper For 2001 - 10000 - cost 4.5 cents/paper For 10000+ - 4 cents/paper So Cost = (5 cents * 2000 ) + (4.5 cents * 8000 ) + (4 cents * 15000) = $1060 alternatively, (0.05 x 2000)+(0.045x8000)+(0.04x 15000) = 1,060 ANSWER:B
