A) 6 : 1
B) 2 : 3
C) 3 : 2
D) 1 : 6
Correct Answer: A
Solution :
\[\because \] \[270=2\times 3\times 3\times 3\times 5\] and\[405=3\times 3\times 3\times 3\times 5\] \[\therefore \] HCF of 270 and \[405=3\times 3\times 3\times 5=135\] and LCM of 270 and \[405=2\times 3\times 3\times 3\times 3\times 5\] = 810 \[\therefore \] Required ratio \[=\frac{810}{135}=\frac{6}{1}=6:1\]You need to login to perform this action.
