Question

What is percentage of 3x is 6y if x=4y

Answer 1

Given that x=4y

Now,
According to given part we can say that :-
3x = 3(4y) = 12y
(since, x =4y)
Now ,
Second given number is 6y

It is asked that what percentage of 3x is 6y
Or we can say
What percentage of 12y is 6y
This means that
6y will be in numerator and 12y in denominator.

Finding the percentage :-

$(\frac{6y}{12y} \times 100)\% \\ \\ = ( \frac{1}{2} \times 100)\% \\ \\ = 50\%$
Hence,

6y is 50% of 12y
Which means that
6y is 50% of 3x when x is equal to 4y.
