Statement (1) by itself is sufficient. From S1 it follows that \(X = 16N + 2\) where \(N\) is an integer. Thus, the remainder of \(\frac{X}{8}\) is 2.
Statement (2) by itself is sufficient. From S2 it follows that \(X = 24N + 10 = (24N + 8) + 2\) where \(N\) is an integer. Thus, the remainder of \(\frac{X}{8}\) is 2.

Answer: D
Hi
I think I am missing some concept here. I framed equations like this: Stem=X=8a+R; To find R=X-8a Stmt1=X=16b+2 Stmt2=X=24c+10
Hence got E as cant find a or X from any of the stmts. I knw logically what I did is not wrong but dont know how to proceed from here. Read something about primes but how does the concept come about? Pls elaborate. Thanks.

Hi, NOTE:- whatever is the remainder by an integer, the remainder will remain teh same if div by its factors.. only thing to check is if the R is further div by that factor what you should have done after making your statements.. Stmt1=X=16b+2 we do not require X or a, we are interested in R.. so what does x/8 mean.. (16b+2)/8=16b/8 + 2/8.. 16b is div by 8 so will not leave any remainder but 2/8 will leave a remainder of 2.. suff Stmt2=X=24c+10 same way ( 24c+10)/8= 3c +10/8.. when 10 is div by 8, it will give us 2 as remainder .. again suff
could someone explain to me how does it follow from statement 1 that
that X=16N+2X=16N+2 where N is an integer?
hi I. (1) The remainder of \(\frac{X}{16}\) is 2... it can be written as -- when x is divided by 16, the remainder is 2... we do not know the quotient(Q) here but just know the remainder.. how do I write it in a equation- x = 16a + 2.. a is the quotient and 2 is the remainder.. say a is 5.. so x= 5*16 +2 = 82.. I can write it as-- the remainder of 82/16 is 2..
so x=16n+2 is just another way of writing -- The remainder of \(\frac{X}{16}\) is 2

I think this is a high-quality question and I don't agree with the explanation. what if we take x=14 for statement 1. then 14/16 gives rem as 2 but 14/8 gives rem as 6. so the correct answer should be B.

14 divided by 16 gives the remainder of 14, not 2. From (1) x could be 2, 18, 34, 50, 66, ... Each of these values gives a remainder of 2 when divided by 8, so (1) is sufficient.
