The “X% of Y = Y% of X” Rule*

Using the scenarios above, trying to figure out how much you can save with 40% off of a ₹75 order is a bit tricky upfront. 

Yet when you reverse it using the X% of Y = Y% of X rule, it gets easier. 

For example, 75% of 40 is simply asking for 3/4 of 40, which we know is 30.

Since we now know that 75% of 40 is equal to 30 , we also know that 40% of ₹75 is equal to 30.

Simple right? Here’s another example: 

Store: “We currently have a special clearance where you can save 60% off of a ₹300 order of clothes!”

You: “Well, I know that X% of Y = Y% of X.

Why calculate 60% of ₹300, when I can just calculate 300% of 60?

After all, 300% is just multiplying 60 by 3. This gives me 180.

And just like that, I now know that 60% of a ₹300 order would save me ₹180.”

Another, more common example:

Store: “Hey customer, order ₹50 worth of stuff now and we’ll knock off 30%!”

You: “Well, trying to figure out what 30% of ₹50 is just an uglier calculation than what I’m used to.

Luckily with this rule, I know that 50% of 30 is a much cleaner and easier way to figure out the same answer. Simply, 50% of 30 is equal to 15.

In a matter of seconds, I know that 30% off of a ₹50 order saves me ₹15.”
