Question

if y% of x=30,then x% of y=?.explain

Answer 1

This is one handy trick i am about to teach you :

Lets take x = 50 and y = 10

Now y% of x = 10% of 50

                    = 10/100 * 50

                    = 5

Now x% of y = 50% of 10

                     = 50/100 * 10

                     = 5

What do you understand ???

x% of y = y% of x   Use this trick in hectic percentage calculations like

48% of 500 = 500% of 48 this way it ll be easy

Now the answer to your question will be 30
