    Question

    Initially, a bag contains t-shirts of two colours (yellow

    and green) in the ratio of 7: 15 respectively. If 19 yellow t-shirts and 11 green t-shirts were distributed among employees in a team, and the ratio of yellow, and green t-shirts became 1: 4 respectively, then what is the number of yellow t-shirts in the bag initially?
    A 14 Correct Answer Incorrect Answer
    B 42 Correct Answer Incorrect Answer
    C 63 Correct Answer Incorrect Answer
    D 35 Correct Answer Incorrect Answer
    E 28 Correct Answer Incorrect Answer

    Solution

    Let initially, number of yellow t-shirts = 7x and number of green t-shirts = 15x
    (7x - 19)/(15x - 11) = 1/4
    => 28x - 76 = 15x - 11
    => 13x = 65
    => x = 5
    So, number of yellow t-shirts in the bag initially = 7 * 5 = 35
