🧠 NUMBER SYSTEM = BACKBONE OF CSAT

Agar hum UPSC CSAT ke PYQs (Previous Year Questions) ko dhyaan se analyse karein,
toh ek cheez crystal clear ho jaati hai 👇

🔥 NUMBER SYSTEM se 25+ questions directly / indirectly aate hain 🔥

Yes, you read it right.

📊 Approximate Weightage (CSAT):

Number System: 20–25 questions

Unit Digit & Powers: 5–8 questions

Remainders & Cyclicity: 5–7 questions

Divisibility & Last Digit logic: 3–5 questions

Mixed concepts (Time & Work, Ratio, Percentages):
👉 Sab number system pe hi based hote hain

Iska matlab simple hai 👇
👉 Agar Number System strong hai = CSAT safe hai
👉 Agar Number System weak hai = CSAT danger zone 🚨

🎯 UNIT DIGIT – SABSE CHHOTA TOPIC, SABSE BADA IMPACT

Aspirants aksar sochte hain:

“Sir, unit digit toh chhota topic hai, baad mein dekh lenge”

❌ यही सोच CSAT डुबो देती है।

Unit Digit:

Chhota dikhta hai

Simple lagta hai

Lekin exam mein time kha jaata hai

UPSC yahin pe check karta hai 👇
👉 Aap logic se solve karte ho ya calculation se?

💣 UNIT DIGIT = 30 SECONDS vs 3 MINUTES

Ek hi question:

Weak aspirant: ❌ 3–4 minutes

Smart aspirant: ✅ 20–30 seconds

Difference?
👉 Cyclic patterns ka gyaan
👉 Power ke last digit ka logic
👉 Practice + right approach
