A) 4 : 9 : 45
B) 16 : 36 : 45
C) 16 : 36 : 20
D) 4 : 36 : 40
Correct Answer: B
Solution :
a : b = 2 : 3 b : c = 4 : 5 and, a : b = 8 : 12 b : c =12 : 15 \[\therefore \] \[a:b:c=8:12:15\] \[\therefore \]\[{{a}^{2}}:{{b}^{2}}:bc={{8}^{2}}:{{12}^{2}}:15\times 12\] \[=64:144:180=16:36:45\]You need to login to perform this action.
