(1) On the fifth day of reading the book, John reads more than 180 pages
(2) John reads 52 more pages on the fourth day of reading the book than he reads on the third day
  • a)
    Statement (1) ALONE is sufficient, but statement (2) alone is
    not sufficient to answer the question asked.
  • b)
    Statement (2) ALONE is sufficient, but statement (1) alone is
    not sufficient to answer the question asked.
  • c)
    BOTH statements (1) and (2) TOGETHER are sufficient to
    answer the question asked, but NEITHER statement ALONE
    is sufficient to answer the question asked.
  • d)
    EACH statement ALONE is sufficient to answer the question
    asked.
  • e)
    Statements (1) and (2) TOGETHER are NOT sufficient to
    answer the question asked, and additional data specific to the
    problem are needed.

Verified Answer
John starts reading a book from the first page onwards and reads each ...
Step 1 & 2: Understand Question and Draw Inference
  • Let’s assume John reads x pages on the first day.
    • Number of pages read by John on second day = 2x
    • Number of pages read by John on the third day = 22 x
    • Number of pages read by John on 4th day = 23 x
    • Number of pages read by John on 5th day = 24 x
  • Total pages read by John in 5 days = x +2x +4x +8x +16x = 31x
  • Number of pages in the book = 400
To Find: Is 31x ≥ 400 ?
  • If Yes, then John will have finished the book before 6 day. So, he will not be reading the book on the 6 day
  • If No, then John will still be reading the book on the 6 day
Step 3 : Analyze Statement 1 independent
  • On the fifth day of reading the book, John reads more than 180 pages
    • Number of pages read on 5 day = 16 x> 180.
      • x > 11
      • So, x = 12 < 12. Something or x = 13 > 12.something
  • Insufficient to answer
Step 4 : Analyze Statement 2 independent
(2) John reads 52 more pages on the fourth day of reading the book than he reads on the third day
  • Number of pages read on third day = 4x
  • Number of pages read on fourth day = 8x
  • Extra number of pages read on the fourth day compared to the third day = 8x – 4x = 4x
4x = 52, i.e. x = 13
Therefore, the answer to the question  
Sufficient to answer.
Step 5: Analyze Both Statements Together (if needed)
As we have a unique answer from step-4, this step is not required.
Answer: B
