If 40 chairs are bought for Rs
Luda [366]

Answer:

25 chairs

Step-by-step explanation:

If 40 chairs are bought for Rs 10000 then how many chairs must be sold for Rs 10000 so as to gain 60%?

The percent gain = 60%

Number of chairs to be sold = x

Hence:

40 chairs = 10,000

60/100= 40 - x/x × 100

0.6= 40 - x/x

Cross Multiply

0.6x = 40 - x

0.6x + x = 40

1.6x = 40

x = 40/1.6

x = 25 chairs

LMNP is a rectangle. Find the value of x and the length of each diagonal.
Neporo4naja [7]

Solution:

<u>We know that:</u>

  • Given diagonals: LN and MP
  • LN and MP must be equal because they are diagonals of LMNP.
  • LN = 4x + 3
  • MP = 8x - 9

<em>Since LN and MP must be equation</em>, <u>equation formed:</u> 4x + 3 = 8x - 9

<em>Let's simplify the equation to find x.</em>

<u>Subtracting 4x both sides.</u>

  • 4x + 3 = 8x - 9
  • => 4x - 4x + 3 = 8x - 9 - 4x
  • => 3 = 4x - 9

<u>Add 9 both sides.</u>

  • => 3 = 4x - 9
  • => 3 + 9 = 4x - 9 + 9
  • => 12 = 4x

<u>Divide 4 both sides.</u>

  • => 12 = 4x
  • => \frac{12}{4}  = \frac{4x}{4}
  • => x = 3

<em>Now, let's find the length of each diagonal.</em>

  • LN = 4x + 3 = 4(3) + 3 = 12 + 3 = 15 \space\ units
  • MP = 8x - 9 = 8(3) - 9 = 24 - 9 = 15 \space\ units
