A) 2
B) 3
C) 4
D) 5
Correct Answer: A
Solution :
Sol. [a] Let the numbers be \[12x\] and \[12y\] where x and y are co-primes. |
Product of these numbers \[=144\,xy\] |
Hence, \[144xy=6336\,\,\Rightarrow \,\,\,xy=44\] |
Since. 44 can be written as the product of two factors in three ways. i.e., \[1\times 44,\]\[2\times 22,\]\[4\times 11.\]As x and y are coprime.so \[(x,y)\] can be \[(1,\,44)\]or \[(4,11)\]but not \[(2,22)\]. |
Hence, two possible pairs exist. |
