Question for Practice Questions Level 1: Percentage - 1
Try yourself:A man buys a mobile phone at Rs. 5436 including 12.5% tax. How much money could he have saved by not paying the tax?
Explanation
Suppose, price of the mobile phone without tax is x.
Then, according to the question: x = 5436
⇒ x = 5436 × 8/9 = 604 × 8 = 4832
∴ Price of the mobile phone without tax = 4832
∴ Amount of tax paid = 5436 - 4832 = Rs. 604
Alternative solution:
With tax of 12.5% = Rs. 5436
Since, 12.5% can be written as 1/8 part.
So, 1/(1 + 8) part of 5436 is the tax.
5436/9 = 604
Tax = Rs. 604
