B2 x C is definitely divisible by 3.
(I) C = P - Q where P = lmn and Q=nml ("lmn" is a three digit number having l as hundredth, m as tenth and n as unit digit.)
(II) B = √(2+ (√2+(√2 ... infinite terms)))
Statement (I) alone is sufficient to answer the question, but statement (II) alone is not.
Statement (II) alone is sufficient to answer the question, but statement (I) alone is not.
Statements (I) and (II) taken together are sufficient to answer the question, but neither statement alone is sufficient.
Each statement alone is sufficient to answer the question.
Statements (I) and (II) taken together are not sufficient to answer the question.
Answer :Statement (I) alone is sufficient to answer the question, but statement (II) alone is not.
Solution (Fast Approach)
Statement I => C = 100l+10m+n - 100n-10m-l = 99l -99n = 99 (l-n) .... Hence, can be divided by 3
Statement II => As the series is infinite. we can rewrite the equation as
B = √(2+B)
Squaring both the sides
B2 = 2 + B
B2 - B -2 = 0
B = 2 or -1
We can take B as 2 only, since a square root cannot be a negative no.
Hence Statement II is not sufficient to answer the question
