    number and 38% of the number is 112. What is 20% of the number?
    A 65 Correct Answer Incorrect Answer
    B 90 Correct Answer Incorrect Answer
    C 70 Correct Answer Incorrect Answer
    D 68 Correct Answer Incorrect Answer

    Solution

    Let the number be x. Then, x × 7/10 – 38% of x = 112 => 7x/10 – 38x/100 = 112 => 70x – 38x = 112 × 100 => 32x = 11200 ∴ x = 350 ∴ 20% of 350 = 350 × 20/100 = 70
