1231 . A time-study specialist has set the production rate for each worker on a certain job at 22 units every 3 hours. At this rate what is the minimum number of workers that should be put on the job if at least 90 units are to be produced per hour?

A. 12
B. 13
C. 18
D. 30

View Answer	Favorite Question	Report

Answer: Option B

Explanation:

The rate for each worker can be expressed as 22/3 units per hour.

We can let n = the number of workers needed to produce 90 units per hour, and we have:

n(22/3) = 90

or,22n = 270

∴ n = 270/22 = 12.2,

so there must be at least 13 workers.(ans)

Let cost price(CP) of toy is 100 tk

And maximum profit 40%

Selling price at 40% discount is 100 - 40 = 60 tk

Selling price (SP) After Another additional 25% discount is

60 - 25% of 60

= 60 - 15

= 45

Now

If CP is 100tk then possible SP is 45tk

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

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।

1245 . 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%.
