The profit for the five years of a firm are as follows – year 2013 Rs. 4,00,000, year 2014 Rs. 3,98,000, year 2015 Rs. 4,50,000, year 2016 Rs. 4,45,000 and year 2017 Rs. 5,00,000. Calculate goodwill of the firm on the basis of 4 years purchase of 5 years average profits.

Answer» `{:("Year","Profit(Rs.)),(2013,400000),(2014,398000),(2015,450000),(2016,445000),(2017,500000),(Total,2193000):}`
Average `=("Total Profit of Last 5 Years")/("No. of years") = Rs. (21,93,000)/(5) = Rs. 4,38,600`
Goodwill = Average Profits `xx` No. of years purchased
= Rs `4,38,600 xx 4 =` Rs. 17,54,400
The above calculation of goodwill is based on the assumption that no change in the overall situation of profits is expected in the future. The above illustration is based on simple average. Sometimes, if there exists an increasing on decreasing trend, it is considered to be better to give a higher weightage to the profits to the recent years than those of the earlier years. Hence, it is a advisable to work out weighted average based on specified weights like 1, 2, 3, 4 for respective year’s profit. However, weighted average should be used only if specified.

Evaluate the following1. 7!/5!2. \(\frac{12 !}{10 ! \times 2 !}\)3. 6P44. 9P45. 10P5

Answer»

1. \( \frac{7 !}{5 !} = \frac{7 \times 6 \times 5 !}{5 !}\) = 45

2. \(\frac{12!}{10! \times 2!} = \frac{12 \times 11 \times 10!}{10! \times 2!}\) = \(\frac{12 \times 11}{2!}\) = 66

3. 6P4 = 6 × 5 × 4 × 3 = 360

4. 9P4 = 9 × 8 × 7 × 6 = 3024

5. 10P5 = 10 × 9 × 8 × 7 × 6 = 30240

How many five digits telephone numbers can be constructed using the digits 0 to 9 if each number starts with 67 and no digit appears more than once?

Answer»

Digits 6, 7 already used, so only 8 digits available to fill remaining 3 places.

676 ways7 ways8 ways

Hence by fundamental principle of counting there are 8 × 7 × 6 = 336 different 5 digit telephone numbers.

7.

How many two-digit even numbers with distinct digits can be formed from the digits 1, 2, 3, 4, 5.

Answer»
Filled in 4 waysFilled by 2,4 - 2 ways

Hence by fundamental principle of counting, there are 4 × 2 = 8 different 2 digit even numbers.

8.

Answer»
3 ways2 ways1 way

By fundamental principle of counting, there are 1 × 2 × 3 = 6 different 3 digit numbers.

9.

How many numbers can be formed from the digits 1, 2, 3 and 9 if repetition of digits is not allowed?

Answer»
Single digit4 ways
Two digit4 x 3 = 12 ways
Three digit4 x 3 x 2 = 24 ways
Four digit4 x 3 x 2 x 1 = 24 ways

Hence the number of total numbers = 4 + 12 + 24 + 24 = 64.

Prove that : `|{:((y+z)^(2),x^(2),x^(2)),(y^(2),(x+z)^(2),y^(2)),(z^(2),z^(2),(x+y)^(2)):}|=2xyz (x+y+z)^(3)`

Answer» `LHS=|{:((y+z)^(2),x^(2),y^(2)),(y^(2), (z+x)^(2),y^(2)),(z^(2) ,z^(2) ,(x+y)^(2)):}|`
Apply `C_(2) to C_(1), C_(3) to C_(3) - C_(1)`
`|{:(,(y+z)^(2),x^(2) - (y+z)^(2) ,x^(2)-(y+z)^(2)),(,y^(2),(z+x)^(2)-y^(2) , 0),(,z^(2) ,0,(x+y)^(2)-z^(2)):}|`
`|{:(,(y+z^(2)),(x+y+z),(x+y+z)(x-y-z)),(,y^(2) ,(z+x+y)(z+x-y),0),(,z^(2) ,0,(x+y+z)(x+y-z)):}|`
Taking (x+x+y) common form `C_(2)` as well as `c_(3)`
`=(x+y +z)^(2)|{:((y+z)^(2),(x-y-z),(x-y-z)),(y^(2),(z+x-y),0),(z^(2),0,(x+y+z)):}|`
Apply `R_1 to R_2 to R_3`
`= (x+y+z)^(2) |{:(2yz,,-2z,,-2y),(y^(2),,(z+x+y),,0),(z^(2),,0,,(x+y-z)):}|`

Find the rank of the word NAAGI, if these words are written as in a dictionary.

Answer»

The order of the letters will be A, A, G, I, N

A..................ways = 4! = 24
G................Ways = \(\frac{4!}{2!} = 12\)
I................Wats = \(\frac{4!}{2!} = 12\)
NAAGIWays = 1

Therefore the position of ‘NAAGI’ is 24 + 12 + 12 + 1 = 49.

If `A=[[2,3,4],[1,-1,0],[0,1,2]]`, find `A^(-1)`. Hence, solve the system of equations x-y=3, 2x+3y+4z=17, y+2z=7

Answer» `** **A = [{:(,2,3,4),(,1,-1,0),(,0,1,2):}]`
`|A| = 2 (-2) =- 3(2-0) + 4( 1-0) = - 6 ne 0`
`therefore A^(-1) ` exists
Cofactors
`{:(,A_(11) = -2 ,A_(12)=- 2 , A_(13) = 1),(,A_(21) - 2 ,A_(22)=4,A_(23) = -2),(,A_(31) = 4,A_(34) = 4 ,A_(33) = - 5):}`
`Adj A= [{:(,-2,-2,1),(,-2,4,-2),(,4,4,-5):}]`
`Adj A= [{:(,-2,-2,4),(,-2,4,4),(,1,-2,-5):}]`
`A^(-1) = (AdjA)/(|A|) = (1)/(-6) [{:(,-2,-2,4),(,-2,4,4),(,1,-2,-5):}]`
System of equation can be written as AX = B
`"Where A"=[{:(,2,3,4),(,1,-1,0),(,0,1,2):}],X =[{:(,x),(,y),(,z):}] ,B = [{:(,17),(,3),(,7):}]`
Now AX = B
`rArr X = A^(-1)B`
`rArr =(1)/(-6)[{:(,-2,-2,4),(,-2,4,4),(,1,-2,-5):}][{:(,17),(,3),(,7):}]`
`rArr X =(1)/(-6) [{:(,-34,-6,+28),(,-34,+12,+28),(,17,-6,35):}]`
`rArr X = (1)/(-6)[{:(,-12),(,6),(,-24):}]`
`X = [{:(,x),(,y),(,z):}] =[{:(,2),(,-1),(,4):}]`
`rArr x= 2, y = - 1, z = 4`

Read the passage given belowMankind’s experience of various evolutionary changes from primitive times to the present day has been extensive and varied. However, man’s problems were never before as complicated as they seem to be today. Man’s economic activity centres primarily around factor of production ; its role, therefore , has been given a lot of importance. It should be useful to have an overall view of the economic history of man – from the nomadic times to the modern factory system – and study its relevance to the various labour problems of today.Initially, man passed through ‘the hunting and fishing stage’. During this period, his basic needs were adequately met by Nature. Wild animals, birds and fruits satisfied his hunger, and his thirst was quenched by the waters of springs and rivers. Caves gave him shelter and barks of trees were used as clothing. During this stage of man’s progress of the absence of any economic, political and social system.Then came ‘the pastoral stage’, which was marked by a certain amount of economic activity. The nomadic and migratory nature of man persisted, and , together with his goats and cattle, he moved on to fresh pastures and meadows. Some conflicts would sometimes take place among herd owners, for, during this period , the institution of nominal private property ownership was not known.This stage paves the way for ‘the agricultural stage’ during which the class system began to develop. There was a small artisan class mostly self-employed; and there were also landed properties or Zamindars as well as slaves. Thus, arose the feudal system. During the fourth stage of these developments, ‘the handicrafts stage’, a number of social and economic changes took place which marked the beginning of the labour problem in the world. The self – sufficient economy of the village underwent a drastic change. The community of traders and merchants emerged.1.

Why does the author say that labour problems did not exist during ‘the hunting and fishing stage’? a) There was no nation existing at that time b) There were no economic, political and social system c) There was no capitalism and market d) There was no labour 4. “The pastoral stage was marked by a certain amount of economic activity.” How? a) Humans started migrating and held goat-herds b) Humans started owning land c) Conflicts started as humans owned goats d) Humans started doing agriculture. 5. Which word in the passage means ‘surfaced’? a) Quenched b) Emerged c) Nomadic d) Adequately 6. What were the consequences of Feudal system? a) The handcrafters become very rich b) The handicrafts stage led to labour problems c) The villagers were jobless d) The beginning of the labour issues and evolving of the traders and merchants. 7. Arrange in the right order: A) Handicraft stage B) The hunting and fishing stage C) Pastoral stage D) The agricultural stage a) D,B,C,A b) D,B, A, C c) B,C,D,A d) B,C,A,D 8.
