OG12 :10

by aplavakarthik » Thu Aug 11, 2011 10:51 am
When 1/10 percent of 5000 is subtracted from 1/10 of 5000 the difference is

a.0
b.50
c.450
d.495
e.500

Answer: d

Explanation Given in OG:
Since 1/10 percent is 1/1000, the difference asked for is
(1/10)5000-(1/1000)5000 =495

How is 1/10 percent is 1/1000????????

Can some one explain this?

1/10 percent means 1/10 OF 1% --> 1/100*1/10 = 1/1000

1/1000 * 5000 = 5
1/10 * 5000 = 500

500-5 = 495 (D)

When we say x percents, we mean x parts out of 100 parts, i.e. the fraction x/100
For example, 40 percents means 40/100 = 4/10 = 2/5

Similarly, 1/10 percent means (1/10)/100 = 1/1000

1/10 of a percent = 1/1000

1/10 of a percent of 5000: (5000/1)*(1/1000)=5
1/10 of 5000: (5000/1)*(1/10)=500

500-5=495

Answer: D
I don't know what to say, really. Three minutes to the biggest battle of our professional lives. You find out life's this game of inches, so is football. Because in either game - life or football - the margin for error is so small. I mean, one half a step too late or too early and you don't quite make it. One half second too slow, too fast and you don't quite catch it. I'll tell you this, in any fight it's the guy whose willing to die whose gonna win that inch. That's football guys, that's all it is. Now, what are you gonna do?
