तथ्यांक व्याख्या — Caselet DI र Advanced Problems
Caselet DI मा paragraph format मा data दिइन्छ — त्यसलाई table मा convert गरेर solve गर्ने approach।
Caselet DI Strategy
Step-by-step
- Caselet paragraph पूरा पढ्नुस् — सबै numbers underline गर्नुस्
- Table बनाउनुस्: rows=entities, columns=attributes
- Direct दिइएका values fill गर्नुस्
- Derived values calculate गर्नुस् (%, ratio, total)
- प्रश्न solve गर्नुस् table बाट
Sample Caselet
“एउटा school मा 500 विद्यार्थी छन्। 60% छोरा र 40% छोरी। छोराहरूमध्ये 70% ले Math लिन्छन् र 30% ले Science। छोरीहरूमध्ये 50% ले Math र 50% ले Science।”
| Category | Total | Math | Science |
|---|---|---|---|
| Boys | 300 | 210 | 90 |
| Girls | 200 | 100 | 100 |
| Total | 500 | 310 | 190 |
Q: Science लिने students को %? → 190/500×100 = 38%
Two-variable Data (Matrix Table)
| Product \ Region | North | South | East | Total |
|---|---|---|---|---|
| A | 120 | 150 | 80 | 350 |
| B | 200 | 100 | 150 | 450 |
| C | 80 | 120 | 200 | 400 |
| Total | 400 | 370 | 430 | 1200 |
Row % र Column % दुवै निकाल्ने practice गर्नुस्
Common DI Traps
| Trap | Solution |
|---|---|
| Unit confusion (lakh vs crore) | Unit carefully read गर्नुस् |
| % of total vs % of subset | Denominator clearly identify गर्नुस् |
| Growth vs absolute change | Growth=%, Change=absolute |
| Cumulative vs period data | Cumulative = running total |
Caselet DI: Paragraph → Table → Calculate → Answer
• Underline सबै numbers
• Direct values fill → derived values compute
• Row total र Column total verify गर्नुस्
• Underline सबै numbers
• Direct values fill → derived values compute
• Row total र Column total verify गर्नुस्
