The Optimal Decision
Rahul, a young engineer, had just graduated from a prestigious university with a degree in mechanical engineering. He was excited to start his career and make a name for himself in the industry. As he was browsing through job listings, he came across two attractive offers from top companies, X and Y.
Company X offered him a salary of $60,000 per year, with a 10% annual bonus and a signing bonus of $10,000. However, the company was located on the other side of the city, which would require him to spend an additional $5,000 per year on transportation.
Company Y, on the other hand, offered him a salary of $55,000 per year, with a 15% annual bonus and no signing bonus. The company was located close to his home, which would save him $5,000 per year on transportation.
Rahul was torn between the two offers and decided to use the principles of engineering economics to make an informed decision. He started by calculating the present worth (PW) of each offer.
For Company X:
- Salary: $60,000 per year for 5 years (Rahul assumed he would work for 5 years)
- Bonus: 10% of $60,000 = $6,000 per year for 5 years
- Signing bonus: $10,000 (one-time payment)
- Transportation cost: $5,000 per year for 5 years
PW of Company X = -$10,000 (signing bonus) + $60,000 (salary) x (P/A, i, 5) + $6,000 (bonus) x (P/A, i, 5) - $5,000 (transportation) x (P/A, i, 5)
For Company Y:
- Salary: $55,000 per year for 5 years
- Bonus: 15% of $55,000 = $8,250 per year for 5 years
- No signing bonus
- No transportation cost
PW of Company Y = $55,000 (salary) x (P/A, i, 5) + $8,250 (bonus) x (P/A, i, 5)
Rahul assumed an interest rate of 8% per year and used the present worth factor (P/A, i, n) to calculate the PW of each offer.
After performing the calculations, Rahul found that:
PW of Company X ≈ $243,919 PW of Company Y ≈ $251,019
Based on the present worth analysis, Rahul decided that Company Y's offer was more attractive, as it had a higher present worth. He realized that the higher salary and bonus offered by Company X were not enough to compensate for the additional transportation costs.
Rahul accepted Company Y's offer and was able to save money on transportation while enjoying a higher overall compensation package. He was grateful for the engineering economics tools that helped him make an informed decision about his career.

Engineering Economy (often searched as Engineering Economics Tara Chand
is a well-established textbook, particularly popular in Indian engineering curricula for its practical and problem-solving approach. Core Concepts Covered
The text provides a comprehensive foundation in the financial aspects of engineering projects, focusing on: Time Value of Money (TVM):
Explores the principle that money available now is worth more than the same amount in the future. It covers simple and compound interest, present worth (PW), future worth (FW), and annual worth (AW) analysis. Investment Evaluation:
Detailed methods for comparing alternatives, including Net Present Worth, Internal Rate of Return (IRR), and Payback Period. Depreciation and Taxes:
Analysis of how assets lose value over time and the resulting impact on corporate tax obligations. Project Management Tools:
Advanced topics often include the Critical Path Method (CPM), PERT, and Linear Programming to optimize resources. Break-Even Analysis:
Determining the point at which a project becomes profitable by analyzing fixed and variable costs. Editions and Publication Volume 1 (13th Edition): Published by Nem Chand and Brothers Historical Context:
Earlier notable versions include the 2000 edition, which is frequently cited in academic syllabi alongside other standard texts like those by Riggs or Paneerselvam Educational Value The book is highly regarded for its problem-solving approach
, featuring numerous real-world case studies and examples that make complex economic theories applicable to engineering design and decision-making. Note on "141 top":
This phrase appears to be a common artifact from SEO-optimized search strings or specific document ranking lists rather than a standard academic designation or specific page count.

Alternative:
If you can't find the specific PDF you're looking for, consider looking for similar titles or broader topics in engineering economics. There are many textbooks available that cover the subject comprehensively.
1. The "Free PDF" Demand
Most students search for a "free PDF" due to budget constraints or the urgency of last-minute preparation. However, a word of caution: Engineering Economics by Tarachand is a copyrighted publication. While promotional previews or older editions may circulate, looking for a full “free” PDF often leads to:
- Malware-ridden websites: Many so-called "free PDF" portals are traps for virus downloads.
- Outdated editions: Tarachand frequently updates numerical problems (especially in depreciation and inflation). A 2015 PDF will cost you marks in a 2025 exam.
- Legal alternatives: Check your college library portal (NPTEL/NDL), or buy a used copy. The book is generally very affordable (₹250–₹400).
4. Weaknesses
- Dated Context: Engineering economics relies on interest rates, inflation rates, and market examples. Because this book has been in print for decades, some examples use interest rates or project costs that feel outdated (e.g., machinery costs in the thousands rather than millions/lakhs). However, the mathematical principles remain valid.
- Visual Layout: Compared to Western textbooks (like those by Blank & Tarquin or Newman), the layout is somewhat old-school. It is text-heavy with simple black-and-white printing. It lacks the glossy, four-color diagrams found in modern international textbooks.
- Depth of Theory: If you are looking for deep macroeconomic theory or complex case studies on global finance, this is not the book. It is strictly focused on "Engineering Economy" for undergraduates.
Part 4: Where to Find Legitimate Resources (For "141 Top")
Instead of hunting for an elusive, illegal PDF, use these actionable steps to get what you need today.
- Google Books Preview: Search "Engineering Economics Tarachand" on Google Books. Often, pages containing the "141 Top" problems are included in the preview snippet.
- Scribd / Academia.edu (Premium): Professors frequently upload the "Question Bank 141" as a separate 10-page PDF. A free trial of Scribd often grants you access to this specific file.
- University Repositories: Search for "Tarachand Engineering Economics solved manual" on your university's internal digital library.
- Piracy-Free Tip: Go to a physical photocopy shop near any major engineering college (Delhi, Pune, Indore). Ask for "Tarachand EE - only the numeric portion." They sell legal photocopies of only the problem sets for roughly ₹50.
5. Note on the PDF Version
The search term "PDF free" indicates the demand for a digital version.
- Availability: The book is widely available in PDF format on various educational repository sites.
- Quality Issues: Users downloading the "141 top" or similar files should be cautious. Often, scanned PDFs of Indian textbooks are of poor quality—pages may be cut off, diagrams blurred, or pages missing.
- Legality: While free PDFs are convenient, they are often pirated. For students with limited resources, they are a lifeline, but purchasing the physical book supports the author and ensures you have a complete, error-free copy.
