Comment on Two Unknown Values
i can't understand why its
Let's keep going from where
Let's keep going from where we have: x + y = (6.25)(8)
Evaluate to get: x + y = 50
Now that we know the sum is 50, how can we determine which value (x or y) is greater?
Consider these two case...
case i) x = 1 and y = 49 (this satisfies the condition that x + y = 50)
In this case, Quantity A is greater than Quantity B
case ii) x = 40 and y = 10 (this satisfies the condition that x + y = 50)
In this case, Quantity B is greater than Quantity A
Answer: D
Does that help?
Cheers,

Hey can we think of it this
Now for the above question we can see mean to be 6.25 so we can say both x and y can be written as 6.25 so answer is C but as we cannot see how much redistribution is done from or to x and y to make 6.25 so CBD
or i do like ur method as well
