    In 2021, Riya's income was Rs. 20000 out of which she spent

    35% and saved the rest. In 2022, if Riya's income rose by 15% and her spending increased by Rs. 1200, then how much did she save in 2022?
    A Rs. 10800 Correct Answer Incorrect Answer
    B Rs. 15200 Correct Answer Incorrect Answer
    C Rs. 12800 Correct Answer Incorrect Answer
    D Rs. 14800 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Riya's income in 2022 = 20000 × 1.15 = Rs. 23000

    Riya's expenses in 2021 = 20000 × 0.35 = Rs. 7000

    So, Riya's expenses in 2022 = 7000 + 1200 = Rs. 8200

    So, amount saved by Riya in 2022 = 23000 - 8200 = Rs. 14800
