Data sufficiency question. Give answer a/c to Elitmus answer choice.

Y is a prime no. X and Y are whole nos. What is the value of Y.
i) X+1 and X+2 are the factors of Y.
ii) X < 500.
(a) (b) (c) (D)

• 0&2 r d whole number
  2 is the prime number
  So if X= 0 and y=2
  Y has two factor 1and 2
  Statement one is only sufficient to give the answer

• Statement 1 is sufficient
• 9 years agoHelpfull: Yes(0) No(1)
• Can anyone explain this??
• 9 years agoHelpfull: Yes(0) No(4)
• since in 1st equation is given y=(X+1)(X+2)
  SO a prime no can have only two factors i.e 1 and number itself
  so puting x=0
  y=1.2 so y=2
  so 1 is only sufficent condition to answer
