## TYPE 1:

### PROBLEMS BASED ON FINDING HOW MANY NUMBERS ARE THERE:

**1.A trader buys oranges at 7 for a rupee and sells them at 40% Profit.How many oranges does he sell for a Rupee?**

Cost Price of 1 apple=1/7

Selling Price of 1 apple at 40% Profit is equal to 140% of its cost Price .

Selling Price of 1 apple=(1/7) * 140% =(1/7) * (140/100)=1/5

Therefore **5 Oranges are sold for 1 Rupee**

## TYPE 2:

### Chain Rule:

**1.A Manufacturer sells a scooter at 10% Profit to wholesaler who in turn sells it to a retailer at 20% Profit. If the Price Paid by the retailer is Rs.13200,How much the scooter costs to the manufacturer?**

Let the manufacturer bought the Scooter for x Rupees

Given, x*(110/100) * (120/100)=13200

X=(13200*100*100)/(110*120) =10000

The Scooter costs **Rs.10000 **to the manufacturer

## TYPE 3:

### FALSE WEIGHT:

To find Profit/Loss Percentage=[Error /(True Value –False Value)]*100

**Error=True Value – False Value**

**1.A dishonest dealer to sell his goods at cost price,but he uses a weight of 960grams for the 1Kg weight,then the Percentage of gainis?**

Error=1000-960=40grams

Profit%=[40/(1000-40)]*100 ⇒ (40 * 100)/960⇒**4(1/6)%**

**2.A grocer sells rice at a profit of 10% and uses a weight which is 20% less .Find his total percentage Gain?**

Let the Original weight=1000 gm

Here the grocer sells 20% less weight=200 gm, Therefore he sold only 800 gm with 10% Profit

Profit% when he sells rice 20% less than the original quantity

(200/800)*100 =25%

To find Successive Profit/Loss%=x+y+(xy/100)

Here x=10% and y=25% if it is Profit its sign is ‘+’ve if it is Loss then its sign is ‘-‘ve

Profit%=10+25+ (250/100)⇒ 35+2.5=**37.5gm**
