    B 130 Correct Answer Incorrect Answer
    C 150 Correct Answer Incorrect Answer
    D 132 Correct Answer Incorrect Answer

    Solution

    ATQ, Let the HCF be x and LCM be 50x. According to the question, x+50x=765. Solve for x: 51x=765 тЗТ x=15. HCF = 15, LCM = 750. The product of two numbers = HCF ├Ч LCM = 15├Ч750=11250. Given one number is 75, the other number = 11250 /75=150. The other number is 150.
