    Two elements X and Y have atomic weights of 14 and 16. They form a series of compounds A, B, C, D and E in which the same amount of element X, Y is present in the ratio 1 : 2 : 3 : 4 : 5. If the compound A has 28 parts by weight of X and 16 parts by weight of Y, then the compound of C will have 28 parts weight of X and

    A) 32 parts by weight of Y

    B) 48 parts by weight of Y

    C) 64 parts by weight of Y

    D) 80 parts by weight of Y

    Correct Answer: B

    Solution :

    [b] Given \[x=14,\,\,y=16\]
    According to the given data the compounds formed by x and y will be
    \[\underset{\left( A \right)}{\mathop{xy}}\,,\underset{\left( B \right)}{\mathop{x{{y}_{2}}}}\,,\underset{\left( C \right)}{\mathop{x{{y}_{3}}}}\,,\underset{\left( D \right)}{\mathop{x{{y}_{4}}}}\,\And \underset{\left( E \right)}{\mathop{x{{y}_{5}}}}\,\text{ }\]
    \[\therefore \] In compound A, x & y are present in the ratio
      28 : 16
    \[\therefore \] In compound C the ratio will be 28 : 48.
