Answer:

CU = 12

Step-by-step explanation:

Clearly from the diagram of the triangle we can say that,

AD, BE and CF are the medians of the triangle ABC , since they are bisecting the sides of the triangle equally.

Also , U is the intersection point of the these mediands of the triangle whic is known as centroid of the triangle.

Now, from the property of the centroid , centroid divides the median in the ratio of 2 :1 from the point C .

Thus CU will be $\frac{2}{3}$ times of CF (median) .

Given is Cf equals 18 ,

Thus , CU = $\frac{2}{3}$ ×18 = 12.

So, CU equals 12 .

Khan sold his cycle at loss of 8%.had He sold it for 240 more he would have gained 12%

denpristay [2]

Khan sold his cycle at loss of 8%.had He sold it for 240 more he would have gained 12%. Then cost price is $ 1200 and selling price is $ 1104

<h3><u>Solution:</u></h3>

Assume the cost price be "a"

So the selling price of cycle = a - 8% of a

$\text { selling price }=a-\frac{8 a}{100}=\frac{23 a}{25}$

Now according to given, had He sold it for 240 more he would have gained 12%

Selling price + 240 = cost price + 12% profit

$\frac{23a}{25} + 240 = a + \frac{12a}{100}$

$\frac{23a + 6000}{25} = \frac{100a + 12a}{100}\\\\92a + 24000 = 112a\\\\20a = 24000\\\\a = 1200$

So the cost price is $ 1200

Now the selling price = $\frac{23a}{25} = \frac{23 \times 1200}{25} = 1104$

So the selling price is $ 1104

<h3><u>Question</u><u>:</u></h3>

<u>The difference between a 2-digit number and the number formed by reversing its digits is 45. If the sum of the digits of the original number is 13, then find the number. </u>

<h3><u>Statement</u><u>:</u></h3>

<u>The difference between a 2-digit number and the number formed by reversing its digits is 45. </u><u>T</u><u>he sum of the digits of the original number is 13</u><u>.</u>

<h3><u>Solution:</u></h3>

Let one of the digit of the original number be x.
So, the other digit = (13-x)
Therefore, the two digit number = 10(13-x) + x = 130-10x+x = 130-9x
The number obtained after interchanging the digits is 10x+(13-x) =9x+13
Therefore, by the problem

130-9x-(9x+13) = 45

or, 130-9x- 9x-13 = 45

or, -18x = 45-130+13

or, -18x= -72

or, x = 72/18 = 4

or, x = 4

So, the original number = 130-9x = 130 -9(4) = 130 - 36 = 94

<h3>Answer:</h3>

The number is 94.

I think the answer you have given isn't right. The answer should be 94.
