    C 41.25% Correct Answer Incorrect Answer
    D 22.25% Correct Answer Incorrect Answer

    Solution

    ATQ,

    Z's savings increase because: Initially, he saves 40% of his salary. After a 30% salary increase, his new salary becomes 1.3S. He saves 55% of the increased amount (0.3S) in addition to his old savings. New savings = 0.4S + 0.165S = 0.565S. Percentage change in savings: Thus, his savings increase by 41.25% .
