Q. The HCF and LCM of two numbers are 12 and 336 respectively. If one of the number is 84, the other is :
Answer:
48
Notes: First Number $latex \times$ Second Number = HCF $latex \times$ LCM
=> 84 $latex \times$ second number = 12 $latex \times$ 336
Since second number = $latex \frac{12\times 336}{84} = 48&s=1$
Hence option [A] is the right answer.
