A) Rs. 20000
B) Rs. 18000
C) Rs. 26000
D) Rs. 24000
E) None of these
Correct Answer: D
Solution :
| Annual salary of Suresh = Rs. 108000 |
| \[\therefore \] Monthly salary \[=\frac{108000}{12}=Rs.\,9000\] |
| Nandini's monthly salary = Rs. 18000 |
| According to the question, |
| Kaushal's monthly salary \[\times \frac{12}{100}\] |
| = Nandini's monthly salary \[\times \frac{16}{100}\] |
| \[K\times \frac{12}{100}=18000\times \frac{16}{100}\] |
| \[\Rightarrow \] \[K\times \frac{12}{100}=2880\]\[\Rightarrow \]\[K=\frac{2880\times 100}{12}\] |
| \[\Rightarrow \] \[K=Rs.\,24000\] |
