  2. Step-by-step explanation:

    Given :–

    Eighteen balls are kept in a box. Some balls are red and remaining balls are blue. Twice the number of red balls exceeds thrice the number of blue balls by one.

    To find :–

    Find the number of red balls in the box ?

    Solution :–

    Total number of balls kept in the box = 18

    There are red and blue balls

    Red balls + Blue balls = 18

    Let the number of blue balls be X

    Thrice of the blue balls = 3X

    Then the number of red balls = (18-X)

    Twice of red balls = 2(18-X)

    Given that

    Twice the number of red balls exceeds thrice the number of blue balls by one.

    => 2(18-X) = 3X+1

    =>36-2X = 3X+1

    => 36-1 = 2X+3X

    => 35 = 5X

    => X = 35/5

    => X = 7

    Blue balls = 7

    Red balls = 18-7 = 11

    Answer:–.

    Total number of red balls in the box = 11

    Check:–

    Blue balls = 7

    Red balls = 11

    total balls = 7+11 = 18

    Twice the number of red balls exceeds thrice the number of blue balls by one.

    => 2(11) = 22 =21+1

    => 3(blue balls)+1
