Cost of each share = (20 + 2.5% of 20) = tk.20.5
Therefore, number of shares = 8200/20.5 = 400

Let the cost price = 100 units
Marked price = 140 units
Selling price = 140 × 85/100 = 119
Profit % = 19/100×100 = 19%

Let the marked price = 100x
Shop Keeper gives 5% discount, therefore, Price becomes = 95x
Again if shopkeeper gives 6% discount then the price become = 94x
According to the question if he gives 6% discount his earning will Tk.15 less
∴ 95x - 94x = 15
⇒ x = 15
∴ Marked price = 100 × 15 = Tk. 1500

Dividend on 1 share = (12.5 x 50)/100 = tk.6.25
tk.25 is income on an investment of tk.100
tk.6.25 is income on an investment of tk. (6.25 x 100)/25 = tk.25

Single equivalent discount for 20% and 20%
= 20+20−20 × 20/100 
= 40−4 = 36%
Single equivalent discount for 36% and 10%
= 36+10−36 × 10/100
= 46−3.6 =42.4%

Dividend on tk. 20 = tk.9/100x 20= 9/5
tk.12 is an income on tk.100.
Tk. 9/5 is an income on tk. 100/12 x 9/5 = tk.15

F = (BD×TD)/(BD−TD)
= (200 × 100)/ (200−100)
= 200−100/ 100
= Tk.200

Number of shares =4455/8.25= 540.
Face value = tk. (540 x 10) = tk. 5400.
Annual income = tk.12/100x 5400= tk. 648.

Present Worth (P.W.) = 840 - 105 
= Tk. 735
Therefore, S.I. on Tk. 735 = Tk. 105
S.I. on Tk. 8400
= 105 × 840/735
= Tk. 120

Two successive discount is equivalent
= 20+5− 20×5/100
= 25−1 = 24%

S.I. on Tk. 1800 = T.D. on Tk. 1872
P.W. of Tk. 1872 is Tk. 1800
Tk. 72 is S.I. on Tk. 1800 at 12%
Time = (100×72)/(12×1800)
= 1/3 years = 4months

T.D. = (B.G.×100)/(R×T)
= Tk.(6×100 / 12×1)
= Tk.50

Cost price of motor-car = Tk. 17000
Mark price of motor-car
= Tk 17000 × 100/85 = Tk. 20000
After successive discount,Cost price
= Tk. 20000 × 95/100×90/100
= Tk. 17100 

Sum = (B.D.×T.D.)/(B.D.−T.D.)
= (120×110) / (120−110)
= 1320

P.W. = Tk.(540−90) = Tk.450
∴S.I. on Tk.450
= Tk. 90 
S.I.on Tk. 540
= Tk.(90/450×540)
= Tk.108
∴B.D.= Tk.108

Let the cost price of goods = Tk. 100
Mark price of goods = Tk.130 (30% discount)
Selling price of goods 
= 90% of 130 = Tk 117
Gain = 117 - 100 = Tk. 17
Gain% = 17/100×100 = 17%

(B.D.×T.D)/(B.D.−T.D)
= Tk (72×60/ 72−60)
= Tk. (72×60/12)
= Tk.360

By investing tk. 1552, income = tk. 128.
By investing tk. 97, income = tk.128/1552 x 97= tk. 8.
Dividend = 8%

Dividend on 1 share
= ( 10/ 100 ×50)
= Tk. 5
Tk. 12.50 is an income on an investment of tk. 100
Tk. 5 is an income on an investment of :
= Tk. (100× 2/25 ×5)
= Tk. 40.
∴ Cost of 1 share = Tk. 40

BG = Tk. 360
T = 3 years
R = 12%
TD = (BG×100)/TR
= (360×100)/(3×12)
= Tk. 1000
BG = BD - TD
⇒ BD = BG + TD = 360 + 1000 = Tk. 1360

Number of shares = (14400/120) = 120
Face value = (100 × 120) = 12000
Annual income = (5/100 × 12000) = 600

F = (BD×TD)/(BD−TD)
= (200×100)/(200−100)
= 200−100/ 100
= Tk. 200 

Income from bank = 14% of Tk. 13200 = Tk. 1848
Number of shares purchased
= Tk. (13200/110)
= Tk. 120
Income from stock
= (15% of Tk. 100) × 120
= Tk. (15 × 20)
= Tk. 1800
∴ Loss = Tk. (1848 - 1800)
= Tk. 48

By investing Tk.1552, income = Tk 128.
By investing Tk.97, income = Tk.(128 / 1552×97) = Tk 8
∴Dividend = 8%

Let, Marked price = Tk. x
∴x× 70/100 × 85/100 =476
⇒ x = 476 × 100/70 ×100/85 
⇒ x= Tk. 800 

Let the cost price = 100 units
Marked price = 120 units
Selling price = 120 × 80/100 = 96 units
There will be loss
Loss% = 100−96 /100 × 100 = 4%
