Let the cost price = Tk.100

Therefore, Selling price = 100×117100 = Tk.117100×117100 = Tk.117

Therefore, Marked price = 117×10090 = 130117×10090 = 130

Therefore, Profit Percentage = (130−100)100×100 = 30%

Answer: Option D

Explanation:

Let's calculate the cost price (CP) and selling price (SP) for the mangoes:

Cost Price (CP) of 15 mangoes = Tk. 10 Cost Price (CP) of 1 mango = Tk. 10 / 15 = Tk. 2/3

Selling Price (SP) of 10 mangoes = Tk. 15 Selling Price (SP) of 1 mango = Tk. 15 / 10 = Tk. 3/2

Now, let's calculate the profit percentage:

Profit per mango = Selling Price (SP) per mango - Cost Price (CP) per mango Profit per mango = (Tk. 3/2) - (Tk. 2/3) Profit per mango = (3/2) - (2/3) Profit per mango = (9/6) - (4/6) Profit per mango = (5/6)

Now, calculate the profit percentage:

Profit Percentage = (Profit per mango / Cost Price per mango) * 100 Profit Percentage = [(5/6) / (2/3)] * 100 Profit Percentage = [(5/6) * (3/2)] * 100 Profit Percentage = (15/12) * 100 Profit Percentage = (5/4) * 100 Profit Percentage = 125%

So, the shopkeeper earns a profit of 125%

Answer: Option A

Explanation:

Let, the original number = 100
20% reduced = 100 - 100 of 20% = 80
Then, 20% increased = 80 + 80 of 20% = 96
The difference = 96-80 = 16
16 difference then original number = 100
1 difference then original number = 100/16
8 difference then original number = (100×8)/16 = 50

192 . A tank can be filled with water by two pipes A and B together in 36 minutes, the tank is filled in 40 minutes. The pipe B can alone fill the tank in -

A. 45 munutes
B. 60 munutes
C. 75 minutes
D. 90 munutes

View Answer	Favorite Question

Answer: Option D

Explanation:

Let the pipes fill the tank in x minutes.
Part of the tank filled by pipes A and B in one minute: 1/36
Part of the tank filled by pipe A in 1 minute = 1/36−1/x
According to the question,
30 × (1/x) + (1/36−1/x) = 1
⇒30x + 10/9−40/x = 1
⇒10/x = 1/9
Hence, x = 90 minutes.

Answer: Option D

Explanation:

Let, Tk was deposited at 5%

so, (1200 - x) was at 7%

Total interest = 72 = . 5 × x + ( 1200 - x) ×. 07

= . 05x + 84 - . 07x

x (. 05 - . 07) = 72 - 84

x × ( - .02) = - 12

x = 12/.02 = 600

195 . A train 125 m long passes a person , running at 8 km / hr in the same direction in which the train is going in 25 seconds . The speed of the train is :

A. 22
B. 36
C. 30
D. 26

View Answer	Favorite Question

Answer: Option D

Explanation:

Speed of the train relative to man = (125/25) m/sec = 5 m/sec.
[5 x (18/5)] km/hr = 18 km/hr.
Let the speed of the train be 'S' km/hr.
Then, relative speed = (S - 8) km/hr.
S - 8 = 18 = > S = 26 km/hr.
