| If 1/2 of A = 2/5 of \[B=\frac{1}{3}\] of C, then \[A:B:C\]is equal to [SBI (SO) 2016] |
A) 4: 5: 6
B) 6: 4: 5
C) 5: 4: 6
D) 4: 6: 5
E) None of these
Correct Answer: A
Solution :
| \[\frac{1}{2}\,\,A=\frac{2}{5}\,\,B=\frac{1}{3}\,\,\,C=k\]\[\Rightarrow \]\[A=2k\] |
| \[B=\frac{5}{2}k\]\[\Rightarrow \]\[C=3k\] |
| \[A:B:C=2k:\frac{5}{2}\,\,k:3K=4k:5k:6k=4:5:6\] |
