The perimeter of a rectangle poll Is 154m.Its length is 2m more than twice its breath find l an db

Answer»

Answer:

Breadth =25 m

Length =104 m

Step-by-step EXPLANATION:

Let the breadth be x.

Length =2*(2x+2)

Perimeter of a rectangle=2*(L+b)

A. T. P,

2(2x+2+x)=154*

2(3x+2)=154*

3x+2=154/2

3x+2=77

3x=77-2

3x=75

X=75/3

X=25

breadth =25m

Length =2(225+2)

=2*(50+2)

=2*52

=104 m.

39.	An article was sold for rupees 5000 at a profit of 12 %. Find the cost price of the article. If the same article sold for rupees 4750. Find the gain or loss percent
Answer» Answer: COST Price of article = RS 4464 Gain% = 6.4% Step-by-step explanation: Let the cost price of article be Rs. x . We are given that an article was sold for Rs 5000 at a profit of 12 % . As we KNOW that profit or loss is always applied on cost price so; Cost Price + 12% of Cost Price = SELLING Price x + 0.12 * x = 5000 1.12 * x = 5000 x = 5000/1.12 = Rs 4464.28 ≈ Rs 4464. So, the cost price of article is Rs 4464. Now, If the same article sold for Rs 4750 we have to find gain or loss % As we can clearly SEE that now also the selling price of article is more than the cost price so there is a gain in selling of article. Gain % = $\frac{Gain}{Cost Price} 100$ = $\frac{4750-4464}{4464} 100$ = 6.4068% ≈ 6% Therefore, gain% = 6.4% .

An article was sold for rupees 5000 at a profit of 12 %. Find the cost price of the article. If the same article sold for rupees 4750. Find the gain or loss percent

Answer»

Answer:

COST Price of article = RS 4464

Gain% = 6.4%

Step-by-step explanation:

Let the cost price of article be Rs. x .

We are given that an article was sold for Rs 5000 at a profit of 12 % .

As we KNOW that profit or loss is always applied on cost price so;

Cost Price + 12% of Cost Price = SELLING Price

x + 0.12 * x = 5000

1.12 * x = 5000

x = 5000/1.12 = Rs 4464.28 ≈ Rs 4464.

So, the cost price of article is Rs 4464.

Now, If the same article sold for Rs 4750 we have to find gain or loss %

As we can clearly SEE that now also the selling price of article is more than the cost price so there is a gain in selling of article.

Gain % = $\frac{Gain}{Cost Price} *100$

= $\frac{4750-4464}{4464} *100$ = 6.4068% ≈ 6%

Therefore, gain% = 6.4% .
