11.	Namita offers a discount of 20%on all the items at her shop and still makes a profit of 12%.What is the C. P. of an article marked at Rs 280?
Answer» Answer: COST Price = Rs. 200 Step-by-step explanation: Marked price of the ARTICLE ( MP ) = ₹ 280 Discount percentage ( d % ) = 20 % Profit percentage ( p % ) = 12 % Now, first of all let the cost price of the article ( CP ) be ₹ ' X '. Discount = 20 % of MP Discount = 20 % of ₹ 280 Discount = 20/100 * 280 Discount = 0.2 * 280 Discount = 2 * 28 Discount = ₹ 56 Hence, SP = MP - Discount SP = ₹ 280 - ₹ 56 SP = ₹ 224 Selling price of the article = ₹ 224 We know that, Profit = p % of CP Profit = 12 % of x Profit = 12X / 100 Profit = ₹ 0.12 x Now, SP = CP + Profit ₹ 224 = x + 0.12 x ₹ 224 = 1.12 x 224 = 112x / 100 22400 = 112 x x = 22400 / 112 x = ₹ 200 Hence, Cost price of the article = ₹ x = ₹ 200

11.

Namita offers a discount of 20%on all the items at her shop and still makes a profit of 12%.What is the C. P. of an article marked at Rs 280?

Answer»

Answer:

COST Price = Rs. 200

Step-by-step explanation:

Marked price of the ARTICLE ( MP ) = ₹ 280

Discount percentage ( d % ) = 20 %

Profit percentage ( p % ) = 12 %

Now, first of all let the cost price of the article ( CP ) be ₹ ' X '.

Discount = 20 % of MP

Discount = 20 % of ₹ 280

Discount = 20/100 * 280

Discount = 0.2 * 280

Discount = 2 * 28

Discount = ₹ 56

Hence,

SP = MP - Discount

SP = ₹ 280 - ₹ 56

SP = ₹ 224

Selling price of the article = ₹ 224

We know that,

Profit = p % of CP

Profit = 12 % of x

Profit = 12X / 100

Profit = ₹ 0.12 x

Now,

SP = CP + Profit

₹ 224 = x + 0.12 x

₹ 224 = 1.12 x

224 = 112x / 100

22400 = 112 x

x = 22400 / 112

x = ₹ 200

Hence,

Cost price of the article = ₹ x = ₹ 200

Find the forcewhen the distance is halved.
Answer» Answer: (i) F=kQ1Q2/d^2 .......(ii) The force of repulsion would be 80N. Step-by-step explanation: As,from FORMULA (i) U can see that F is inversely proportional to d.So by keeping the other parameters constant the new force would be inversly prop. to d^2.Thus,if distance would be HALVED then the force would be DOUBLED but due to square,if the distance would be halved then force would be quadrupled.

ХIf 3x + 2is equal toX/2-3 then find the value of x

Answer»

Step-by-step EXPLANATION:

Here,

3X + 2 = x /2 - 3

3x + 2 =( x - 6 ) /2

2( 3x + 2) = x - 6

6x + 4 = x - 6

6x - x = - 6 - 4
