Case study 1:- Read the following and answer the question(Case study problem matrix 1)

Â  Â A manufacturer produces three stationery products Pencil, Eraser and Sharpner which he sells in two markets. Annual sales are indicated below

 Market Products (in numbers) Pencil Eraser Sharpner A 10,000 2,000 18,000 B 6,000 20,000 8,000

If the unit sale price of Pencil, Eraser and Sharpner are â‚¹ 2.50, â‚¹ 1.50 and â‚¹1.00 respectively, and unit cost of the above three commodities are â‚¹ 2.00, â‚¹ 1.00 and â‚¹ 0.50 respectively, then,

(i) Total revenue of market A is

(a) â‚¹ 64,000Â  Â  Â  Â  Â  Â  Â  (b) â‚¹ 60,400

(c) â‚¹ 46,000Â  Â  Â  Â  Â  Â  Â  Â (d) â‚¹ 40,600

(ii) Total revenue of market B is

(a)Â  â‚¹ 35,000Â  Â  Â  Â  Â  Â  Â  (b) â‚¹ 53,000

(c) â‚¹ 50,300Â  Â  Â  Â  Â  Â  Â  Â (d) â‚¹ 30,500

(iii) Cost incurred in market A is

(a) â‚¹ 13,000Â  Â  Â  Â  Â  Â  Â  Â  (b) â‚¹30,100

(c) â‚¹ 10,300Â  Â  Â  Â  Â  Â  Â  Â  Â (d) â‚¹ 31,000

(iv) Profit in market A and B respectively are

(a) (â‚¹ 15,000, â‚¹ 17,000)Â  Â  Â  Â  Â  (b) (â‚¹ 17,000, â‚¹ 15000)

(c) (â‚¹ 51,000,Â  â‚¹ 71,000)Â  Â  Â  Â  Â  (d) (â‚¹ 10,000, â‚¹ 20,000)

(v) Gross profit in both market is

(a) â‚¹ 23,000Â  Â  Â  Â  Â  Â  Â  (b) â‚¹ 20,300

(c) â‚¹ 32,000Â  Â  Â  Â  Â  Â  Â  Â (d) â‚¹30,200

Total revenue for market A

= 10,000Ã—2.50 + 2000Ã—1.50 + 18000Ã—1.00

= â‚¹46000

Total revenue for market B

= 6,000Ã—2.50 + 20,000Ã—1.50 + 8000Ã—1.00

= â‚¹ 53000

Cost incurred in market A

= 10,000Ã—2.00 + 2000Ã—1.00 + 18000Ã—0.50

= â‚¹ 31,000

= 6,000Ã—2.00 + 20,000Ã—1.00 + 8000Ã—0.50

= â‚¹ 36,000

Profit in market A = â‚¹ 46000 – â‚¹ 31000 = â‚¹ 15000

Profit in market B = â‚¹ 53000 – â‚¹ 36000 = â‚¹ 17000

Gross profit = Profit in market A +Â Profit in market B

= â‚¹ 15000 + â‚¹ 17000
