A) Rs. 30250
B) Rs. 40000
C) Rs. 35600
D) Rs. 44750
Correct Answer: C
$ \Rightarrow $ $ x\times \frac{30}{100}=15a $
$ \Rightarrow $ $ x\times 3=15\times a\times 10 $
$ \Rightarrow $ $ x=5a\times 10 $ (ii) It is also given that she spends Rs. 3560 on transportation.
$ \therefore $ $ 5a=3560 $ Now, putting the value of $ 5a $ in Eq. (i), we get $ x=3560\times 10=35600 $ Hence, monthly salary of Ruhi = Rs. 35600
