UGC NET Paper-1 ka Unit-5 — Mathematical Reasoning & Aptitude — ek aisa unit hai jahan basic maths aur logical thinking ka combination hota hai. Yahan number series, coding-decoding, percentage, ratio, average, time & work jaise topics se direct MCQ bante hain. Jo candidates is unit ko ignore karte hain, wahi final merit mein peeche reh jaate hain.
Is complete Unit-5 guide mein hum cover kar rahe hain: pura syllabus, important topics, smart tricks, shortcuts aur exam pattern — taaki aap December 2026 exam mein is unit se full marks laa sakein.
Unit-5 Syllabus at a Glance
NTA ke official syllabus ke according, Mathematical Reasoning & Aptitude unit ke andar ye topics aate hain:
Important Topics (High-Yield)
Pichle saalon ke papers ka analysis karein toh yeh topics baar-baar repeat hote hain. Inhe pehle master karo:
- Number Series: Difference, ratio, square/cube pattern, alternate series — inhe pehchano.
- Coding-Decoding: Letter shifting, number coding, symbol substitution — direct questions aate hain.
- Percentage & Ratio: Basic percentage change, ratio proportion — ssc-level maths kaafi hai.
- Time, Speed & Distance: Relative speed, average speed, train problems — formula-based questions.
- Time & Work: Work efficiency, pipes & cisterns — LCM method se solve karo.
Smart Tricks & Shortcuts
Unit-5 mein time bachana sabse important hai. Yeh shortcuts yaad rakho:
Number Series Tricks
- Pehle consecutive difference nikalo
- Difference constant nahi toh ratio check karo
- Square/cube series ke liye numbers yaad rakho
Percentage Shortcuts
- 10% = number ÷ 10, 5% = 10% ÷ 2
- Successive % change = a + b + ab/100
- Fraction equivalents yaad karo (1/8 = 12.5%)
Time & Work Trick
- LCM method use karo — total work assume karo
- Efficiency inversely proportional to time
- A+B together = (A×B)/(A+B) days
Speed & Distance Shortcuts
- Same direction: relative speed = difference
- Opposite direction: relative speed = sum
- km/h to m/s = × 5/18
Common Mistakes to Avoid
Calculation Mistakes
- Rough work clean nahi rakhna — errors badhte hain
- Units convert na karna (km/h vs m/s)
- Shortcut galat apply karna
Strategy Mistakes
- Ek question pe 3+ minute lagana
- Daily practice na karna
- Formulas yaad na karna

?Frequently Asked Questions
-
1. Unit-5 se kitne questions aate hain?
Average 5–7 questions per shift. Number Series, Coding-Decoding aur Percentage se sabse zyada questions aate hain. No negative marking — attempt all.
-
2. Kya maths weak students Unit-5 kar sakte hain?
Bilkul. Unit-5 mein advanced maths nahi hai — basic 10th-level maths kaafi hai. Daily 30 minute practice se aap easily 5–6 questions solve kar sakte ho.
-
3. Kya Unit-5 ke liye alag se book padhni chahiye?
Nahi. KVS Madaan + RS Aggarwal (basic) + PYQs + notes kaafi hain. Zyada sources se confusion badhta hai.
-
4. Time kaise manage karein is unit mein?
Har question ka target 1 minute rakho. Agar 1.5 minute se zyada lag raha hai toh skip karo — pehle easy questions solve karo, phir hard pe aao.
