The factors of 481=(481×1) and (37×13) According to the question x>y, then (x,y)=(481,1) or (37,13) Statement 1: y>1 Hence, only possible value are x=37,y=13 We can easily find the value of (3x−2y). Statement 2. HCF of x and y is 1 In both (481,1) or (37,13),HCF is 1 . Two different values of (3x−2y) ∴ Statement- 1 alone is sufficient to answer the question
