A) 10 : 15 : 20
B) 22 : 23 : 24
C) 6 : 4 : 3
D) 2:3:4
Correct Answer: C
Solution :
Let the amounts invested by x, y, z respectively. Then, \[\frac{x\times 2\times 5}{100}=\frac{y\times 3\times 5}{100}=\frac{z\times 4\times 5}{100}=k\] \[\therefore \] \[x=10k,y=\frac{20}{3}k,\] and \[z=5k\] So \[x:y:z=10k:\frac{20}{3}k:5k\] \[=30:20:15\] \[=6:4:3\]You need to login to perform this action.
