Shoe factory finds that X out of Y shoes produced are defective.
Expresssed as a percentage this would be: * 100
:
x people can build a wall in Y days.
How many people will be required to build a wall in y/3 the time: 3x people
:
Dennis is 4 years younger than Ray
d = r - 4
who is going to be X years old a year from now.
r + 1 = x
r = x - 1
What calculation would you use to find out how old Dennis is now?
replace r with (x-1) in the first equation
d = (x-1) - 4
d = x - 5
:
If we find i=j and j>k, Then which of the following is true.
i k k>j
i+k
