A) 68
B) 72
C) 86
D) 91
Correct Answer: D
Solution :
Let the numbers be 3x and 4x respectively First number x second number \[=HCF\times LCM\] \[\Rightarrow \] \[3x\times 4x=2028\] \[\Rightarrow \] \[{{x}^{2}}=\frac{2028}{3\times 4}=169\] \[\therefore \] \[x=\sqrt{169}=13\] \[\therefore \] Sum of the numbers \[=3x+4x=7x=7\times 13=91\]You need to login to perform this action.
