Example Question #1 : How To Find Percentage
In a jar of 240 coins, 20 percent are nickels and 5 percent are dimes. How many coins are not nickels or dimes?
75% of the coins are not nickels or dimes. This means that 
Example Question #8 : How To Find Percentage
What number is 125% of 120?
Verbal cues include "of" and "is." Of means multiplication and is means equals
So the equation to solve becomes
Example Question #2 : How To Find Percentage
What percent of 250 is 20?
Verbal cues include "of" and "is." Of means multiplication and is means equals
The equation to solve becomes 
Example Question #1151 : Sat Mathematics
What number is 30% of 90?
Verbal cues include "is" and "of." "Is" means equals and "of" means multiplication.
So the equation to solve becomes
Example Question #1152 : Sat Mathematics
If the length of a rectangle is increased by 50% and with width of the same rectangle is decreased by 50%, what is the effect on the area of the rectangle?
It is increased by 25%
It is decreaed by 25%
It is unchanged
It is decreased by 50%
It is increased by 50%
It is decreaed by 25%
This is a good question to use random numbers. Lets use 100 and 10 as the lengths. That means the area = 100 x 10 = 1000
If we increase the length of the side measuring 100 by 50% = 150
If we decrease the length of the other side 50% = 5
Area = 150 x 5 = 750
We see that the area decreased by 250 or 25% decrease in area!
