1232 . A trader buys some goods for Tk. 150. If the overhead expenses be 12% of cost price, then at what price should it be sold to earn 10%?

A. Tk. 188.80
B. Tk. 185.80
C. Tk. 187.80
D. Tk. 184.80

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

দ্রব্যের ক্রয়মূল্য 150 টাকা

অতিরিক্ত ব্যয়ভার ( 150 এর 12%) টাকা

= ( 150 × 12/100) = 18 টাকা

মোট খরচ ( 150 + 18) টাকা বা 168 টাকান

10% লাভে বিক্রয়মূল্য ( 168 + 168 এর 10%) = 168 + 16.8 = 184.80 টাকা

1233 . A trader marked the price of a article 30% above the cost price and gave the buyes 10& discount on market price, thereby gaining Tk. 340. The cost of the article is?

A. 3000
B. 2000
C. 1900
D. 1800

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

মনে করি,

দ্রব্যটির ক্রয়মূল্য = ১০০ টাকা

সুতরাং, তালিকা মূল্য = ১০০ + ৩০ = ১৩০ টাকা

অতএব, দ্রব্যটির কমিশন মূল্য অর্থাৎ বিক্রয়মূল্য = ১৩০ - ১৩০ × ১০/১০০ টাকা = ১৩০ - ১৩ টাকা = ১১৭ টাকা

লাভ = ( ১১৭ - ১০০) = ১৭ টাকা

১৭ টাকা লাভ হয় যখন ক্রয়মূল্য ১০০ টাকা

৩৪০ টাকা লাভ হয় যখন ক্রয়মূল্য = ১০০ × ৩৪০/১৭ = ২০০০ টাকা।

1234 . A trader raised the price of his product by 10% and then he lowered the enhanced price by 10%. Compared to the latest price the first price has been--

A. lowered by 1%
B. kept equal
C. enhanced by 1%
D. enhanced by 4%

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Let's call the original price of the product "P".

The trader raised the price of the product by 10%, so the new price would be P + (P * 0.10) = 1.10P.

The trader then lowered the enhanced price by 10%, so the latest price would be 1.10P - (1.10P * 0.10) = 0.99P.

To compare the latest price to the original price, we can divide the latest price by the original price and multiply by 100 to get the percentage:

Percentage = (0.99P / P) * 100
Percentage = 99%

So the latest price is 99% of the original price. This means that, compared to the latest price, the original price has been raised by 1%.

A. 56. 25%
B. 25.56 %
C. 50.25%
D. 54.25%v

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Let the marked price = Tk. 100
Then, SP = 100 - 20% of 100 = Tk. 80
Profit = 25%
Let His CP = X
SP = 80
X + 25% of X = 80
Hence, X = Tk. (100 × 80)/125
= Tk. 64
CP = Tk. 64
Profit after selling on marked price = 100 - 64 = Tk. 36
% gain = (36 × 100)/64
= 56.25%

D. 55 km/hr

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

Given:

Length of train = 125 m

Time taken = 10 secs

Speed of man = 5 km/hr

Concept Used:

When 2 objects are moving in same direction, then

Relative speed = Difference between their speeds

Formula Used:

Speed = Distance/Time

1 Km/hr = (5/18)/s

Calculations:

Let the speed of train be v km/hr.

Speed of the man = 5 km/hr

Now, (v-5) × (5/18) = (125/10)

বা, (v-5) = (125/10) × (18/5) = 45 km/hr

বা, v = (45+5)= 50 km/hr.

C. 100 s
D. 130 s

View Answer	Favorite Question	Report

Answer: Option B

Speed of train = length of train/time taken

Calculation:

Speed of train = 240/24 = 10 m/s

Time taken to cross the platform = (240 + 650)/10 = 890/10
= 89 s

:The time taken to cross the platform is 89 s.
