Why Unit-5 Is a Scoring Unit?Unit-5 Mathematical Reasoning aur Aptitude se har shift mein 5–7 questions aate hain. Yeh unit pure practice-based hai — koi ratta nahi, sirf speed aur accuracy chahiye. Agar aap daily 30–40 minutes practice karte ho, toh is unit se full marks laa sakte ho.

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.

01

02

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.
03

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
04

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.
