## What is Discount?

In the garment stores, you’ve come across this sign many times: “** http://cinziamazzamakeup.com/?x=prezzo-viagra-svizzera HURRY! 20% OFF!!**”

That 20% is called discount.

Suppose a Music CD has price tag of Rs.100 and the shopkeeper is offering 20% discount.

That means 20% less on the price tag.

The price you’ve to pay

=Rs.100 minus 20% of 100

=100-(20×100/100)

=100-20

=Rs. 80 you’ve to pay, to buy that music CD.

** dove comprare viagra generico a Milano But** in exam, we don’t have no time to do such lengthy calculations.

So just think in your head:

20 percent discount means you’ve to pay 100 percent minus 20 percent=80 percent of the price tag.

% means one upon hundred (1/100)

So 80% means (80/100=0.8)

So you’ve to pay 0.8 times the original price.

=0.8 x 100

=Rs. 80

## What is successive discount?

It means discount on the discount. (just like Compound Interest rate= interest on interest)

The original price of a music CD is Rs.100. A shopkeeper offers 10% discount on this music CD and then again offers 20% discount on the new price. How much will you have to pay, finally?

## Phase I: 10% discount

So new price = 0.9 x original price. (by the way, how did we get 0.9 ? well 10% discount means you’ve to pay 90%. And 90% means 0.9)

## Phase II: 20% discount

=0.8 x new price

=0.8 x 0.9 x original price.

It means, after successive discount of 10% and 20%, the final price you’ve to pay

=0.72 x original price.

=0.72 x 100

=Rs.72

If it was successive discount of 20% and then 10%? Still answer will remain same. ORDER or sequence doesn’t matter.

Let’s test our skill with an actual question from SSC/FCI Exam taken in Nov 2012.

Q1. A dealer buys a table listed at Rs.1,500 and gets successive discounts of 20% and 10%. He spends Rs.20 on transportation and sells it at a profit of 20%. The selling price of the table is

- Rs.1,320
- Rs.1,350
- Rs.1,360
- Rs.1,380

Think in your head:

20% discount =0.8 x original price (this is our new price)

10% successive discount= 0.9 x New price=0.9 x 0.8 x original price

Finally dealer had to pay: 0.72 x original price.

Then he invested Rs.20 on transport, so his total investment (cost price) is

(0.72 x original price) + Rs.20

And ultimately he sold It @20% profit.

20% profit means 100%+20%=120%

=1.2 times the investment (cost price).

=1.2 times [(0.72 x original price) + Rs.20]
In the examhall,only write following line and do the math, don’t waste time writing everything or multiplying numbers @every stage.

** go to site =1.2 times [(0.72 x 1500) + Rs.20]**

=1.2 [1080+20]
=1.2 [1100]
=Rs. 1320

(I hope you know quick multiplication with 11, basically 12×11= in 12 you do:1|(1+2)|2=132)

## Case: Successive vs One Time Discount?

Q. Jethalal, has a mobile phone with price tag Rs.12,399/-. He is offering two schemes to you

- Buy it at one time discount of 30%
- Buy it at two successive discounts of 15% and 15%

Which of the above scheme is more beneficial to you (customer)?

## Long cut (tiresome and boring calculation)

Scheme A | Sheme B |

Discount offered =30% of 12,399 =0.3 x 12,399 =3719.7 |
Phase I 15% of 12399 =1859.85 Rs. (discount I) So new price : 12399 MINUS 1859.85=10539.15 Phase II: (second discount) =15% of 10539.15 =0.15 x 10539.15 =1580.8725 (discount II) Total discount =1859.85 +1580.8725 =3440.7225 |

We are getting more discount in Scheme A compared to Scheme B.

So, from customer’s point of view, Scheme A is more beneficial.

^Very lengthy and tiresome calculation isn’t it?

Well, if you look at it carefully, the price tag Rs.12,399/- is ** http://cinziamazzamakeup.com/?x=viagra-generico-in-farmacia-senza-ricetta-pagamento-online-a-Firenze irrelevant** here.

## Shortcut (almost none calculation)

Scheme A | Scheme B |

Discount offered=30% Final price you’ve to pay =0.7 times original price. |
Successive discount 15% (two times) Final price you’ve to pay =0.85 x 0.85 x original price =0.7225 x original price |

In Scheme A, you’ve to pay less price compared to Scheme B. Because 0.7 < 0.7225

So, from customer’s point of view, Scheme A is more beneficial.

** siti sicuri per comprare viagra generico 100 mg pagamento online a Firenze Sidenote**: you can do 85×85 with Vedic shortcut (square of numbers ending with five)

Square of 85

=8|5

=(8x(8+1)|25

=8*9|25

=7225

I hope discount and successive discount is clear. Moving to the next topic.

## What is marked price?

Before that, answer this question:

## Why do shopkeepers give discount?

Well it’s a marketing propaganda to seduce customers.

I’m running a jeans store. I bought a pair of jean for Rs.100 (cost price).

Now I put a new tag on it Rs.500 (marked price) and then put a huge poster outside my shop: “50% OFF on any item!”

From buyer’s point of view it looks very attractive “wow 50% discount!!”

But in reality, I’m making huge profit. Because 50% discount on Rs.500= You’ve to pay Rs.250, while I had invested only Rs.100! so my profit=(250-100)=Rs.150

Marked price=this new price tag Rs.500. Discount is given on marked price. If we want to visualize it, here is the diagram:

** acquistare viagra generico a Bologna Mind it**: Profit or loss is always calculated on actual investment (Cost price), unless they specifically instruct you do something else.

Time to test the skill with actual questions

## Case: Finding Marked Price from Profit %

Q. Jethalal bought a Nokia mobile phone @ Rs. 800. He sold it to Master Bhide after allowing a discount of 10%. In this deal, Jethalal made a profit of 12.5%. What was the marked price?

- Rs. 1,000
- Rs. 1,100
- Rs. 1,200
- Rs. 1,300

Profit is always calculated on actual investment (cost price).

Cost Price: Rs.800

The question says, profit =12.5%. What is the profit in rupee terms?

Long cut | Shortcut |

=12.5% x 800 =(125/10)x (1/100) x 800 =Rs. 100 |
12.5% =1/8 (percentage to fraction conversion table). So, 12.5% x800 = (1/8) x 800= Rs. 100 |

Anyways in either method, profit is Rs.100…Fact (i)

Jethalal gave 10% discount on marked price. So customer Bhide Master had to pay only

90% of the Marked Price.

=0.9 times the marked price

=this is the money Jethalal received from customer.

## Jethalal’s actual profit

=the money he received from customer MINUS his original investment.

=0.9 times Marked price MINUS Rs.800

But recall fact (i), Jethalal’s profit is Rs.100

Therefore

100=0.9 times Marked price – Rs.800

100+800=0.9 times marked price

900=0.9 x MP

MP=900 x 10/9

MP=Rs. 1000.

Final Answer: marked price is Rs.1000

In the exam hall, directly frame the equation: 0.125 x800 =(0.9 xMP)-800

Let’s try another one.

## Case: Finding marked price from Selling price

Q. Master Bhide, bought two pens for Rs.37.40 at a discount of 15%. What must be the marked price of each of pen?

- Rs.11
- Rs.44
- Rs.33
- Rs.22

Discount of 15%, means Master Bhide (customer) paid (100-15)=85% of the marked price.

=0.85 times the marked price

But question also says he paid Rs.37.40, Therefore

37.40=0.85 x MP.

MP=3740/85

=(374x 10)/ (17×5)

=(374 x 2)/17

=(22×2)

=44. (Sidenote, if you don’t know the multiplication table of 17, then use approximation method explained in earlier article. CLICK ME)

** http://acrossaday.com/?search=lasix-prescription-drug Most important part:** Rs.44 is the marked price of two pens. So marked price of each pen =44/2=Rs.22

Answer is (D)

In the actual exam, rough paper calculation: =37.4/(0.85 x 2)

## Case: Finding % Profit / loss in MP-Discount

Jethalal marks the price tags of all his mobile phones, 10% above the cost price. And then He offers 10% discount on their marked prices. What is his profit or loss?

- 1% profit
- 1% loss
- 5% profit
- No profit No loss.

Assume his total investment is Rs.100 (=cost price). Well we can assume total investment as “CP” or “x” or “y” or anything but assuming Rs.100 saves the time of calculating percentages later on.

Marked price

=10% above cost price

So price tag (marked price) is

100%+10% of Cost price

=110% of cost price

=1.1 x cost price

=1.1 x 100

=Rs. 110

Now he offers 10% discount on marked price, so customer has to pay only

0.9 times the marked price

=0.9 x 110

=Rs.99

Verdict: His investment is Rs.100 and he receives only Rs.99 from customers so he is making loss

How much loss?

Long cut | Loss % formula =(100-99)/100 x 100=1% |

Shortcut | We assumed Rs.100 initially for the very reason that to prevent long cut formula! Since he receives one rupee less (100-99), his loss is 1%. |

In the actual exam, rough paper:

Invested | Received |

100 | 0.9 x 1.1 x 100=99 |

So, loss is 1%.

I hope the concept of marked price is clear by now. So it is time for a
