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.
