    A Rs.205 Correct Answer Incorrect Answer
    B Rs.195 Correct Answer Incorrect Answer
    C Rs.325 Correct Answer Incorrect Answer
    D Rs.270 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let Priya’s income = Rs. x

    Sweta’s income = x + 30, Tania’s income = 4x

    Total income = x + (x + 30) + 4x = 6x + 30

    Average = Rs. 360 ⇒ Total = 3 × 360 = 1080

    6x + 30 = 1080

    ⇒ 6x = 1050

    ⇒ x = Rs. 175

    Sweta’s income = 175 + 30 = Rs. 205
