    Natu and Bachku each have certain number of oranges. Natu says to Bachku, “If you give me 10 of your oranges, I will have twice the number of oranges left with you”. Buchku replies, 'If you give me 10 of your oranges, I will have the same number of oranges as left with you". What is the number of oranges with Natu and Bachku, respectively?  [SSC CGL Tier II, 2017]

    A) 50, 20

    B) 70, 50

    C) 20, 50

    D) 50, 70

    Correct Answer: B

    Solution :

    [b] Let, Natu have oranges \[=70\]
    and Bachku have oranges \[=50\]
    By giving 10 oranges by Buchku to Natu,
    Number of oranges Natu have \[=70+10=80\]
    Number of oranges Bachku have \[=50-10=40\]
    According to the question, \[80=2\times 40\]
    i.e., Number of oranges Natu have
    \[=2\times \] Number of oranges Bachku have
    (Given condition satisfied)
    Now, giving 10 oranges by Natu to Bachku,
    Number of oranges Natu have \[=70-10=60\]
    Number of oranges Buchku have \[=50+10=60\]
    According to the question, \[60=60\]
    i.e., Number of oranges Natu have
    = Number of oranges Bachku have
    (Given condition satisfied)
    Hence, option is the right answer.
