A) 17
B) 23
C) 27
D) 33
Correct Answer: C
Solution :
[c] Let numbers be x and y. \[\therefore Product\,\,of\,\,two\,\,numbers=their\,\,(LCM\times HCF)\]\[\Rightarrow \,\,\,xy=630\times 9\] \[Also,\,\,x+y=153\,\,(given)\] \[since\,\,x-\,y=\,\,=\sqrt{{{(x+y)}^{2}}-4xy}\] \[\Rightarrow x-y=\sqrt{{{(153)}^{2}}-4\,\,(630\times 9)}\] \[=\sqrt{23409-\,22680}=\sqrt{729}=27\]You need to login to perform this action.
