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

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.

Explanation

Total Price = 700

700 x 40/100

Profit =280

Explanation

Let the percentage deduction in weight be y%

y−4100−y×100=20⇒y−4100−y=15⇒5y−20=100−y⇒6y=120⇒y=20

Hence, for a meter, length used = (100 - 20)% of 1 m

= 80% of 100 cm = 80 cm

Explanation

Let the cost price of the dog be Rs. X

∴ the cost price of the cat = Rs. (6500 – X)

The man sold the dog at a gain of 20%

∴ Gain in selling the dog = 20% of X = 0.2X

Also, the man sold the cat at a loss of 10%

∴ loss in selling the cat = 10% of (6500 – X) = 0.1 × (6500 – X) = 650 – 0.1X

He gained 2% in the overall.

∴ Gain in overall transaction = 2% of 6500 = 130

∴ 130 = 0.2X – (650 – 0.1X)

0.3X = 130 + 650 = 780

X = 780/0.3 = 2600
