The excess of an expenditure flow over the income flow is term as Deficit.

آمدنی کے بہاؤ پر اخراجات کے بہاؤ کی زیادتی کو خسارہ کہا جاتا ہے۔

Explanation

Formula used:

Profit % = SP−CP/CP×100

Profit % = SP−CPCP×100, where SP is the selling price and CP is the cost price.

Complete step-by-step solution:

We are given that man (the buyer) purchases a cow for Rs. 3000 on a credit basis at a rate of interest 10% per annum for 2 years.

10% of Rs. 3000 is 

   10/100

×3000=Rs.300

10100×3000=Rs.300

For 2 years, the interest is 

2×300=Rs.600

2×300=Rs.600

Therefore the actual price (cost price) of the cow is 

3000+600=Rs.3600

3000+600=Rs.3600

The selling price of the cow is Rs. 3600.

Therefore, the profit or gain by selling the cow is

⇒Profit % = 3600−3600/ 3600 ×100=0%

Explanation

Given that:

C.P=450 & S.P=495

When S.P is greater than C.P, we get Profit

Profit=S.P-C.P

Profit=495-450

Profit = 45 

Now,

Gain% = [100*Gain]/C.P

             = [100*45]/450

             = 10%

Explanation

As S.P<C.P, so we get a loss 

Loss  = C.P-S.P 

          =60-50

         = 10

Now,

 Loss%= [ 100*Loss]/C.P 

            =[ 100*10]/60

            =16.6%

Explanation

Explanation:

Let the C.P. of the article be Rs. x.

Then, required ratio = 104% of x / 106% of x
= 104/106 = 52/53 = 52:53

Explanation

Given :

• Two chairs and one table cost Rs.400, while one table and one chair cost Rs.300.

To Find :

• The price of the table.

Solution :

Let us assume that, the price of one table is "x" and the price of one chair is "y" respectively.

As it is given that, two chairs and one table cost Rs.400.

→ x + 2y = 400 .......(1)

As it is also given that, one table and one chair cost Rs.300.

→ x + y = 300 ........(2)

Our equation are,

• x + 2y = 400 .......(1)
• x + y = 300 ........(2)

Subtract equation (2) from equation (1),

→ (x + 2y) - (x + y) = 400 - 300

→ x + 2y - x - y = 400 - 300

→ x - x + 2y - y = 400 - 300

→ 2y - y = 400 - 300

→ y = 400 - 300

→ y = 100

Now, substitute the value of y in equation (2),

→ x + y = 300

→ x + 100 = 300

→ x = 300 - 100

→ x = 200

Hence, the price of the table is Rs.200.
