A) \[-2\]
B) \[-1\]
C) \[1\]
D) \[2\]
Correct Answer: A
Solution :
LCM of two prime numbers \[x\]and\[y=161\] \[\because \]HCF of \[x\]and\[y=1\] LCM\[=x\times y=161\] Factorizing, we get \[x\times y=161=7\times 23\] \[\therefore \]\[x=23,\,\,y=7\] \[3y-x=3\times 7-23=-2\]You need to login to perform this action.
