A) 75
B) 81
C) 85
D) 89
Correct Answer: C
Solution :
Let the numbers be x, y and z which are prime to one another. Now, \[xy=551,\]\[yz=1073\] \[\therefore \]y = HCF of 551 and 1073 \[\therefore \] y = 29 \[\therefore \] \[x=\frac{551}{29}=19\] and \[z=\frac{1073}{29}=37\] Sum \[=19+29+37=85\]You need to login to perform this action.
