The mean of the number of sales of cars over a 3-month period is $87, and the standard deviation is 5. The mean of the commissions is $5225, and the standard deviation is $773. A. calculate the coefficient of variation. B. compare the variation of the two and give your comments regarding the variation.

Answer»

Answer:

Heya................❤✌

A) Coefficient of Variation (SALES) = (5/87) *100

= 5.74%

Coefficient of Variation ( commotions) = (773/5225)*100 = 14.8%

B) Commissions are more VARIABLE & less stable & less uniform than sales.

Explanation : Coefficient of variation is large INDICATES that the GROUP is more variable & it is less stable or less uniform. If a coefficient of variation is small then it indicates that the group is less variable & it is more stable & more uniform.

for making 8 trousers of the same size 14 m 80 CM of cloth is needed. how much cloth will be required for each such trouser ?​

Answer»

Correct Question -

For making 8 pairs of trousers of the same size 14 m and 80 centimeters of CLOTH is needed.

How much cloth will be required for each such trouser ?

Solution -

This question can be easily be solved by various methods .

The most easy one is the UNITARY method .

  • Method 1 -

In this method , from the given Information , we need to find the VALUE of a single unit, and then find the required value by multiplying the given single unit value.

So,

In this question -

For making 8 trousers of the same size 14 m and 80 centimeters of cloth is needed.

So,

8 pairs of trousers require 14 m , 80 cm of cloth, i.e, 1480 cm of Cloth .

So,

1 pair of trousers require ( 1480 / 8 ) cm of cloth

=> ( 185 cm ) of cloth .

  • Method 2 -

Proportionality Method -

Here , the length of cloth required to make is directly proportional to the number of trousers made .

So,

1480 = n × 8

=> n = 185 cm .

Hence, For making each such trouser, 185 cm or 1.85 m of cloth is required .

Answer -

For making each such trouser, 185 cm or 1.85 m of cloth is required .

A and B are two pipes connected to a tank. A is the filler pipe and B is the ejector. The capacity of the tank is 6000L.The ejector pipe can eject water at the rate 4L/min higher than the filler pipe. The filler pipe can fill the tank 5 min later than the ejector pipe can eject. Find the flow rate of the ejector pipe in L/min(approx.).

Answer»

Step-by-step explanation:

Given :   ejector pipe can eject water at the rate 4L/MIN higher than the filler pipe . The filler pipe can fill the tank 5 min later than the ejector pipe can eject

To find :  flow rate of the ejector pipe in L/min(approx.).

solution:-

ejector pipe   flow rate    =  E  L/Min

Filler Pipe flow rate  =  E - 4  L/Min

Capacity of Tank  = 6000 L

Time Taken by Ejector pipe =  6000/E    Min

Time Taken by filler pipe = 6000/(E - 4)    Min

The filler pipe can fill the tank 5 min later than the ejector pipe can eject.

=>  6000/(E - 4)     = 6000/E    + 5

=> 6000E   = 6000(E - 4)   + 5E(E - 4)

=> 6000E = 6000E - 24000 + 5(E² - 4E)

=> 5(E² - 4E)  - 24000  = 0

=> E² - 4E - 4800  = 0

=>  E  = (4 ± √(4² - 4*(-4800)) ) /2

=> E =   2 +   √4801  ( ignoring - ve value)

=> E  = 2 + 69.3

=> E = 71.3  

flow rate of the ejector pipe = 71.3 L/min

A dealer X at hapur(UP) supplies goods woth rs. 50000 to some other dealer Y in the same city. Now dealer Y supplies the same goods to dealer Z in calcutta at profit of rs. 20000 find:a) the output and inout taxes for the dealer Yb) the net gst payable by dealer Y[ the rate of GST at each stage is 28 oercent]

Answer»

Given : A dealer X at hapur(UP) supplies goods woth rs. 50000 to some other dealer Y in the same CITY. Now dealer Y supplies the same goods to dealer Z in calcutta at profit of rs. 2000  . [ the rate of GST at each stage is 28 oercent]

To FIND : a) the output and inout taxes for the dealer Y

b) the net gst payable by dealer Y

Solution:

A dealer X at hapur(UP) supplies goods woth rs. 50000 to some other dealer Y in the same city.

GST charged = 28 %  = (28/100)50000 = Rs 14000

CGST = SGST = Rs 14000/2 = Rs 7000

dealer Y pays GST = Rs 14000 to dealer X

Y supplies the same goods to dealer Z in calcutta at profit of rs. 20000

Selling price = 50000 + 20000 = Rs 70000

GST charged = 28 % = (28/100)70000 = Rs 19600

IGST = Rs 19600

Output taxes for dealer Y = Rs 19600

Input taxes for dealer Y = Rs 14000

the net GST payable by dealer Y   = 19600 - 14000 = Rs 5600
