    Solution :

    Let the cost of 1kg apple = Rsx

    cost of 1kg pine-apples = Rsy

    According to the problem given,.

    x + y = Rs 150 —( 1 )

    and

    cost of 1kg apple is twice the cost

    of 1kg pine-apples.

    x = 2y —( 2 )

    Therefore ,

    Required pair of linear equations in

    two variables are ,

    x + y = 150 —( 1 )

    x = 2y —–( 2 )
