Teletalk Question Solution: Mathematics Part
| Question | Solution |
|---|---|
| 11. The value of 16⅔% of ___ is 150. | 16⅔% = 1/6. Therefore x/6 = 150, so x = 900. |
| 12. What happens to the area of a circle after a 100% increase in radius? | The radius doubles. New area = π(2r)2 = 4πr2. It becomes 4 times the original, which is a 300% increase. |
| 13. What investment produces a total amount of Tk 826 at 4.5% simple interest over four years? | A = P(1 + rt) = P(1 + .045 × 4) = 1.18P. Thus P = 826/1.18 = Tk 700. |
| 14. Write 9.8 × 10−3 in decimal form. | 0.0098 |
| 15. Simple interest on Tk 300 for four years and Tk 400 for five years totals Tk 144. Find the annual rate. | 144 = r(300×4 + 400×5)/100. Therefore r = 14400/3200 = 4.5%. |
| 16. Four-year interest falls by Tk 2,400 when the annual rate falls by 0.6%. Find the deposit. | 2400 = P × .006 × 4. Therefore P = Tk 100,000. |
| 17. Original question text is missing. | The old record gives 2/3; it cannot be independently verified without the question. |

Important corrections to the old answer list: Question 10 requires “us” to be replaced by “as.” The 2019 Physics Nobel answer includes three laureates, not only James Peebles. Question 30 refers to ISO 20400, which is guidance rather than a certificate. Questions 33 and 36 should be answered “forward bias” and “surface-leakage current.” These corrections prevent candidates from memorizing errors repeated across copied question-solution pages.
Teletalk Written Question Solution and Model Guidance
The recorded written section carried 60 marks and covered translation, paragraph or focus writing, mathematical problem solving and technical questions. The original e-commerce passage and numerical values for two mathematics questions are unavailable, so a fabricated full answer would be misleading. The following guidance solves what can be solved and shows the correct method for the incomplete items.
1. Translation and Paragraph Writing
E-commerce translation: The source passage is missing from the recovered paper. Practise translating a passage about online buying and selling, digital payment, logistics, consumer trust and cybersecurity. Preserve meaning, tense and terminology instead of translating every English word literally.
Model paragraph: Paradigm Changes in the Telecommunication Industry of Bangladesh
Bangladesh’s telecommunication industry has moved from voice-centred services to a data-driven digital ecosystem. Mobile internet now supports education, banking, commerce, entertainment, public services and remote work. Competition is no longer limited to call rates; network quality, coverage, data capacity, cybersecurity and customer experience have become major differentiators. Smartphones and mobile financial services have also changed the way people communicate and conduct daily transactions. At the same time, operators face pressure to expand reliable connectivity beyond major cities and make digital services affordable. Technologies such as fibre backhaul, cloud platforms, the Internet of Things and newer mobile standards are gradually reshaping network planning. The next phase of development should focus on inclusive coverage, efficient spectrum use, service quality, consumer protection and secure digital infrastructure. A strong telecommunications sector can therefore contribute directly to productivity, innovation and access to essential services across Bangladesh.
2. Written Mathematics
Hollow box or tank thickness: If the outer length, width and height are L, W and H and uniform wall thickness is t, the inner dimensions become (L−2t), (W−2t) and (H−2t). Insert the given inner surface-area relation and solve the resulting equation for the physically valid positive value of t. The exact numerical answer cannot be recovered because the original dimensions are absent.
Inequality question: Solve each inequality carefully, reverse the inequality sign when multiplying or dividing by a negative number, take the intersection of all conditions and then select the greatest permissible value. The missing inequality prevents a unique numerical solution.
Arrangement question: Seven letters contain A three times, B twice, C once and D once. The number of distinct arrangements is:
3. Focus Writing and Short Notes
Model focus: Telecommunication Development Is a Prerequisite for National Development
Modern economic and social activity depends on fast, reliable and affordable communication. A strong telecommunications network connects citizens with markets, financial services, education, healthcare and government information. It enables businesses to coordinate supply chains, accept digital payments and reach customers beyond their physical locations. Farmers can receive market and weather information, students can access learning resources, and people in remote areas can communicate during emergencies. Telecommunications also supports e-governance by reducing travel, paperwork and service-delivery time. However, infrastructure alone is not enough. National development requires meaningful connectivity: adequate coverage, usable speed, affordable devices, digital literacy, cybersecurity and accessible services. Rural and underserved communities must not be left behind. Investment in spectrum efficiency, fibre connectivity, resilient networks and skilled professionals can raise productivity throughout the economy. For these reasons, inclusive and secure telecommunications development is not merely a supporting service; it is an essential foundation for sustainable national progress.

4. Technical Written Questions
Functions of Node B and GGSN: Node B is the radio base-station element in a UMTS/3G access network. It communicates with user equipment over the air interface and performs radio transmission, reception, coding, modulation and related physical-layer functions under the Radio Network Controller. GGSN means Gateway GPRS Support Node. It connects the GPRS/packet mobile core to external packet-data networks, routes user data, manages relevant session and addressing information, and acts as a gateway between mobile users and networks such as the Internet.
Steps to make a website live: Test the completed site locally; choose hosting and register or configure a domain; deploy the files or application; create any required database and environment settings; point DNS records to the hosting service; enable HTTPS; verify links, forms, mobile layout, security headers and error pages; submit a sitemap to search engines; and establish backup, monitoring and update procedures.
| Aspect | Classical computer | Quantum computer |
|---|---|---|
| Basic unit | Bit, normally 0 or 1 | Qubit, which can use superposition |
| Operation | Classical logic gates | Quantum gates using superposition, interference and entanglement |
| Best use | General everyday and business computing | Selected problems where a suitable quantum algorithm offers an advantage |
| Error handling | Mature and comparatively robust | Highly sensitive to noise and requires complex error control |
| Replacement? | Remains essential | Not a universal replacement for classical computers |
Approaches to testing and debugging a program: Begin with unit tests for individual functions, then integration tests for connected components and system or acceptance tests for complete behaviour. Include boundary values, invalid input and regression tests. During debugging, reproduce the error consistently, inspect logs and stack traces, isolate the smallest failing case, use breakpoints or tracing, check recent changes, correct the root cause and rerun the relevant automated tests.
| Aspect | Horizontal microinstruction | Vertical microinstruction |
|---|---|---|
| Control word | Wide, with little or no encoding | Narrower and more highly encoded |
| Parallelism | Can activate several control signals simultaneously | Usually supports less parallel control |
| Speed | Generally faster because less decoding is required | Generally slower because fields must be decoded |
| Control memory | Requires more memory | Requires less memory |
| Programming | More direct but produces longer control words | More compact but comparatively complex to decode |
The recovered text ends with “Or, EEE related” but does not preserve the alternative EEE question. No invented EEE problem has been added.
