; Searching a substring from a Main string

[org 0x0100]

jmp start



mstr: db 'aaab', 0

sstr: db 'aab', 0

sub_len: dw ; Used to contain length of sub string

; subroutine to calculate the length of a string

; takes the segment and offset of a string as parameters

strlen: push bp

mov bp,sp

push es

push di

les di, [bp+4] ; point es:di to string

mov cx, 0xffff ; load maximum number in cx

xor al, al ; load a zero in al

repne scasb ; find zero in the string

mov ax, 0xffff ; load maximum number in ax

sub ax, cx ; find change in cx

dec ax ; exclude null from length

Question 1; Mark: 10

Use Mathematical Induction to prove that


Solution:


Induction given statement is true for all set of whole numbers.




Question 2; Mark: 5

If is odd then is even (prove by contradiction).



Sol: Suppose 3x + 1 is odd and x is not even

x is not even à x is odd (x is either even or odd but not both)

à x = 2k + 1 ( x is not divisible by 2)

à 3x + 1 = 3 ( 2k +1) + 1 (substitute 2k +1 from x)
3x +1 = 6k + 3 + 1

= 6k + 4

= 2 ( 3k + 2) (Divisible by 2)

à 3x + 1 is even which is contradiction

Therefore 3x + 1 is odd then x is even

Question 3; Marks: 5

Find the number of arrangements of balls having colors Red, Yellow, Blue Green and Pink such that Red and Green balls must place next to each other.

Sol:

Red, Yellow, Blue, Green, Pink
Total numbers of balls = 5
Considering two balls Red and Green as a single ball ( due to restriction), we have to make the arrangements of 4 balls taken all together
No. of Arrangements = 4!
= 4 × 3 × 2 × 1
= 24
But two balls (restricted) permuted among themselves in two ways
i.e. 2! = 2 × 1 = 2 ways
Therefore total numbers of arrangements = 4! × 2!
= 24 × 2
= 48

Solution:


Bell Computers, LTD.,
Cost of Production Report
For the Month of Jan
1. Quantity Schedule
Units of open work in process 10,000
Units put into the process 58,000
68,000
Units of closing work in process 8,000
Units completed and transferred 60,000
68,000

2. Cost Accumulated in the process
Material Cost (18,000+114,000) 132,000
Conversion Cost (8,800+61,600) 70,400
Total Cost 202,400
3. Equivalent unit Produced
Material Cost (60,000+8000*75%) 66,000
Conversion Cost (60,000+8000*50%) 64,000
4. Per Unit Cost
Material Cost (132,000/66,000) = 2
Conversion Cost (70,400/64,000) = 1.1
Total per Unit Cost 3.1
5. Cost Apportionment
Units completed and transferred
(60,000*3.1) 186,000
Closing work in process
Material Cost (6,000*2) 12,000
Conversion Cost (4000*1.1) 4,400 16,400
202,400

Required:
1. How many units were started and completed during January?
Answer:
Unit Started in Jan. = 68,000
Unit Completed in Jan. = 60,000
2. What were the equivalent units for January for material and conversion costs?
Answer:
Equivalent units for January for material costs = 66,000
Equivalent units for January for conversion costs = 64,000

3. What were the costs per equivalent unit for January?
Answer:
Material Cost (132,000/66,000) = 2
Conversion Cost (70,400/64,000) = 1.1
Total per Unit Cost 3.1

4. Verify the accountant’s ending work in process inventory figure (£16,400) given in the report.
Answer:
Closing work in process
Material Cost (6,000*2) 12,000
Conversion Cost (4000*1.1) 4,400 16,400
5. What criticism can be made of the unit costs that have been computed weighted –Average Method by the company and which method is superior computing unit cost under process costing based on your criticism?
Answer:
Comparison of Both methods is under as equivalent production and per unit costs.
Weighed Average Method FIFO Method
Equivalent production per unit costs Equivalent production per unit costs
Material Cost (60,000+8000*50%)
66,000 (132,000/66,000)
2 (1000+50,000+6000)
57,000 (114,000/57,000)
2
Conversion Cost (60,000+8000*75%)
64,000 (70,400/64,000)
1.1 (2000+50,000+4000)
56,000 (61,600/56,000)
1.1
Total 130,000 3.1 113,000 3.1
In comparison we see that the equivalent unit in both methods is different but per unit cost has same. FIFO method is complex than Weighted Average method, so Average method is superior because of less complexity and due to:
1. There are fewer chances to complete the unit which produced first it means first in first, because Authorities prefer to complete the open units and there may be delay in new units to put into the process.
2. Accountants will refer to Average method due to less time consuming and complexity.

SOURCE:-
MGT 301 Handouts and web search.

EXCLUSIVE DISTRIBUTION:-
Exclusive distribution means giving a limited number of dealers the exclusive
right to distribute the company’s products in their territories.

FMCG s:-
FMCGs (Fast Moving Consumer Goods) are inexpensive products that people
usually buy on a regular basis, such as supermarket foods or toiletries.

RECOMMENDATION AS EXCLUSIVE DISTRIBUTION FOR FMCGs OR NOT:-
I will not recommend exclusive distribution for FMCGs because they are
required on regular basis and should be available in every market on most number of
shops and people should have an easy approach towards these products.

EXCLUSIVELY DISTRIBUTED PRODUCTS:-

1. HONDA MOTORCYCLE
REASON: - It is exclusively distributed because its distribution requires financially
strong dealers and dealers whose reputation is well in the market as well as in the society.
And dealers must be able to hold the complex and unexpected environment of the market.
Dealers are required to have a knowledge that why HONDA MOTORCYCLE is better
than others.

2. PEL REFRIGERATOR
REASON: - It is exclusively distributed because there are only a few no of dealers which
are present in the market to sale and service the electric appliances and the distributors
are required to be financially strong and distributors should have knowledge about
electric equipments and inner composition of equipments. They must have well
reputation in the market as appliance dealers.
