    B)  25      

    C)  280     

    D)  65

    Correct Answer: C

    Solution :

    LCM =14 HCF LCM + HCF = 600 14 HCF + HCF = 600 15 HCF =600 HCF\[=\frac{600}{15}\] HCT = 40 LCM\[=14\times 40=560\] According to the question, One number \[\times \]Other number LCM \[\times \]HCF Other number \[=\frac{40\times 560}{80}=280\]
