প্রশ্নে বলা হচ্ছে যে, Pindar এ Marketer দের চেয়ে কত বেশি Programmer রয়েছে? 

এখানে, Pindar এ Marketer আছে প্রায় 35 জন 

এবং Pindar এ Programmer আছে প্রায় = 93 - 35 = 58 জন।

$\therefore$Programmer বেশি আছে = 58 - 35 = 23 জন ।

প্রশ্নে বলা হচ্ছে যে, Jericho তে Marketer দের প্রায় কত শতাংশ Non-management employee ? 

এখানে 93 জনের মধ্যে Marketer আছে 67 জন 

$\therefore$নির্ণেয় শতকরা পরিমাণ = ($\frac{67}{93}\times 100)$% = 72.04%

প্রশ্নে বলা হচ্ছে যে, Fermion ছাড়া দুটি কোম্পানির গড় Marketer দের সংখ্যা নিতে হলে ঐ সংখ্যা Fermion সহ গড়ের সংখ্যার চেয়ে কত বেশি হবে?

Fermion ছাড়া বাকি ১টি কোম্পানির Marketer দের গড় হলো = $\frac{58+35+67+46+52}{5}$=51.6

এখানে Fermion 4 Marketer দের সংখ্যা = 18

$\therefore$Fermion সহ Marketer দের সংখ্যা গড় = $\frac{258+18}{6}=\frac{276}{6}=46$

$\therefore$অতএব, গড় কমবে = 51.6 - 46 = 5.6 (answer)

:There is currently a contentious argument over whether criminals should be imprisoned for committing murders instead of having a capital punishment. I totally agree that offenders ought t spend their lifetime in jails because the punishment of death for a crime does not deter crimes: people have no right to take another human life. 

The main reason why I believe that incarceration should be implemented for all sorts of crimes is an because the death penalty does not stop humans from committing offences. This is due to the fact that many criminals do not think they will be caught and sure that they are able to get away with it. As wel as this, executing prisoners often creates a savage culture, and so it may even boost crime rate. Another reason why I support the notion that killers have to be put behind bars is due to the fact that our society has no prerogative of committing homicide. This is because human life is valuable, and it must not be destroyed by the offender's bad conduct. 

In conclusion, I absolutely agree that even severe law violators are to be jailed. This is because death sentence is not likely to reduce crime rate, and any person has and inalienable right to life. Given this situation, it seems that the authorities should provide highly qualified rehabilitation for the accused giving them a chance to make a difference in their consecutive social life in the future and for the public to be certain that risks of repetitive offences are significantly decreased or even totally eliminated.

Subject: Prayer for the extension of loan payment date. 

Dear Sir, 
With due reverent I want to draw your attention to the fact that many industries along with other business have been badly affected in the COVID-19 pandemic. Many industries have been fully closed and others have been on the verge of the closure. My newly launched industry has also been affected during this time. My company was always smooth in paying regular installments before this crisis. As the sales of my company have reduced sharply and arrears from the buyers have been on the rise, it is being difficult for me to maintain regularity in paying your installments in the time. This is why I request for the extension of loan payment so that I can repay it readily. 

So, I therefore pray and hope that you would be kind to grant me the extension for 12 moths more to pay the loan and oblige me thereby. 

Yours Sincerely 
Pronay Tirki
Chairman of 'P' Group

২০২১ সাল আমাদের মহান মুক্তিযুদ্ধের সুবর্ণজয়ন্তীর বছর। পেছনে তাকালে নিশ্চিত যে গেল ৫০ বছরে আমরা অনেক এগিয়েছি। মাথাপিছু আয়, রাস্তাঘাট, দালানকোঠা, নগরায়ণ, প্রবাসী আয়, আমদানি-রফতানি, রাজস্ব আয়, শিক্ষার হারসহ প্রায় সবকিছুরই অগ্রগতি হয়েছে। প্রযুক্তির ব্যবহার বেড়েছে, চিকিৎসা ব্যবস্থাও এগিয়েছে। বাংলাদেশে ব্যক্তি খাতের প্রসার এবং একটি শিক্ষিত তরুণ উদ্যোক্তা সমাজও গড়ে উঠেছে। এ দেখে নারীর উঠে দাঁড়ানের পর অপরাপর সমমানের দেশের তুলনায় উল্লেখযোগ্য। এরই মধ্যে যাত্রা হয়েছে একটি নতুন বছরের। অনেকের আশা স্বাধীনতার ৫০ বছরে এসে নবোদ্যমে যো করবে বাংলাদেশ।

= 2021 is the golden jubilee of our great liberation war. If we look back, it is sure that we have progressed a lot in that 50 years. Almost all the things including per capita income, roads and highways, buildings and urbanization, remittance earning, import-export, revenue and literacy rate have gone up. The use of technology has increased and the health service has also expedited. Expansion of private sector and an educated entrepreneur society have grown up. The story of rise of women in this country is mentionable comparing to the other equal-ranked countries. In the mean time, the journey of a new year is on. Many anticipate that Bangladesh will start its journey with new enthusiasm in the 50 years of independence.

$Here, 1 hour = 60 minutes.$

$\therefore 24 hour = 24 x 60 = 1440 minutes.$

$The Dolphin comes up air in 1440 minutes =\frac{1440}{2} =720 times$

$\& The Whale comes up air in 1440 minutes =\frac{1440}{5} =288 times.$

$\therefore Required percentage = (\frac{720-288}{288}\times 100) = (\frac{432}{288} \times 100)\% = 150\%$

$The first pump can drain in 3 hours \frac{1}{2} of the pond$

$\therefore The first pump can drain in 1 hours=\frac{1}{2\times 3}=\frac{1}{6} of the pond$

$Both pumps can drain in 1\frac{1}{2}or\frac{3}{2} hours=1-\frac{1}{2}=\frac{1}{2} of the pond.$

$\therefore Both pumps can drain in 1 hours =\frac{1}{2}\times \frac{1}{3}=\frac{1}{3} of the pond.$

$\therefore Working alone the second pump can drain in 1 hour =\frac{1}{3}-\frac{1}{6}=\frac{2-1}{6}=\frac{1}{6} part of the pond$

$\therefore The second pumps can empty \frac{1}{6} of the pond in 1 hour$

$\therefore The second pump can empty 1 or full pond n =\frac{ 6 \times 1}{1} = 6 hours.$
