No calculations required..
it is given that x/y=ny/100...
and x % of y is nothing but RHS *100=n*y..

Solution -

The statement x/y is n% of y means that: x/y = (n / 100) × y

In order to find what percent must x be of y i.e., we need to divide x by y.

x/y %=(n / 100) × y *100 ---->(y*n)%

Therefore x/y is (y*n)%

Given that x/y=n/100*y
Therefore, x/y*100=ny

given that x/y = n% *y
question is asking x/y =what %; therefore from above equation we can very straightforwardly say that x/y =n*y %
hence answer is A

Thanks,

Kudos for a correct solution.


Let, x = 5
and y = 5
i.e. x/y = 1 i.e. 20% of y
i.e. n = 20

Now since x is 100% of y therefore the correct option should result in the value 100 for n=20

A. (y × n)% = 5*20 = 100 CORRECT

B. (n/y)% = 20/5 is NOT 100 INCORRECT

C. (√n)% = \(\sqrt{20}\) is NOT 100 INCORRECT

D. (n^2)% = 20^2 = 400 is NOT 100 INCORRECT

E. (100 – n)% = 100-20 = 80 is NOT 100 INCORRECT

800score Official Solution:

The statement x/y is n% of y means that:
x/y = (n/100) × y
x = y × (y × n / 100)
Therefore x is (y × n)% of y.

The right answer is choice (A).
