Question

The price of a laser printer including 7% tax is 17334 how much less does a customer pay for it if the tax on it is reduced to 4 %

Answer 1

Let the cost excluding tax be x.
then, x+(7/100)x=17334
this gives x=16200.
now, new cost = x+(4/100)x=16848.
therefore,he has to pay (17334-16848)=486 less.

Answer 2

Solution:

Let the price of the laser printer without tax= Rs x

Therefore, Tax = 7% of Rs x

= Rs (7/100 × x)

= Rs 7/100x

So, price of the laser printer including tax

= Rs (x + 7/100x)

= Rs (x + 7/100x)

= Rs (100x + 7x /100)

= Rs 107x / 100

Given: The price of the laser printer including tax

= Rs 17334

Therefore, 107x / 100 = 17334

$= > \: 107x \: = 17334 \times100$

$= > \: \frac{17334 \times 100}{107}$

$= > \: x = 16200$

So, Price of the laser printer without tax is Rs 16200

Given: Tax on it is reduced to 4%

Therefore, 4% of Rs 16200 = Rs ( 4/100 × 16200)

= Rs 648

Again 7% of Rs 16200 = Rs (7/100 × 16200)

= Rs 1134

Therefore, Amount of money less paid by the customer = Rs (1134 - 648)

= Rs 486 (Answer)
