A) 17
B) 23
C) 27
D) 33
Correct Answer: C
Solution :
Let numbers be x and y. \[\because \]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.
