A) Rs. 6000
B) Rs. 8000
C) Rs. 7000
D) Rs. 5000
Correct Answer: A
Solution :
| [a] Let investment of Raghu = Rs. x Then, investment of Mohit = 90% of x = Rs. 0.9x \[\therefore \] Investment of Pradeep = 120% of Mohit investment \[=12\times 0.9x\] Now, ratio of investments of Raghu, Mohit and Pradeep \[=x:0.9x:1.2\times 0.9x\] \[=x:9x:1.08x\] \[=100:90:108=50:45:54\] Hence, investment of Raghu \[=\frac{17880\times 50}{50+45+54}\] \[=\frac{17880\times 50}{149}\] \[=\text{Rs}.\,\,6000\] |
