  • Question
  • Ajay and Vijay have some marbles with them. Ajay told Vijay "if you give me 'x' marbles, both of us will have equal number of marbles". Vijay then told Ajay "if you give me twice as many marbles, I will have 30 more marbles than you would". Find 'x' ?


  • Options
  • A. 4
  • B. 10
  • C. 8
  • D. 5

  • Correct Answer


  • Explanation

    If Vijay gives 'x' marbles to Ajay then Vijay and Ajay would have V - x and A + x marbles.
    V - x = A + x --- (1)
    If Ajay gives 2x marbles to Vijay then Ajay and Vijay would have A - 2x and V + 2x marbles.
    V + 2x - (A - 2x) = 30 => V - A + 4x = 30 --- (2)
    From (1) we have V - A = 2x
    Substituting V - A = 2x in (2)
    6x = 30 => x = 5.
