उत्तर और व्याख्या · explanation in English
Answer: (c) S1 और S2 एकसाथ प्रश्न का उत्तर देने के लिए पर्याप्त नहीं हैं।
S1 caps the book at 2 × 51 = 102 figures and S2 guarantees at least 51. Together they only place the total between 51 and 102, which may or may not exceed 100.
- S1: at most 2 figures on each of 51 pages, so at most 102 figures — could be above or below 100.
- S2: at least 1 figure per page, so at least 51 figures — no upper limit.
- Together: between 51 and 102. Both 101 and 60 are possible, so the Question cannot be answered.
Remember · In data sufficiency, find the range each statement allows; if the range still straddles the question's cut-off, the data are insufficient.
