(b)₹ 20000
(c)₹ 24000
(d)₹ 26000
(e)None of these
Answer
Answer (as printed): C
Explanation
Sonal's annual salary $=₹ 108000$. Sonal's monthly salary $$=₹\left(\frac{108000}{12}\right)=₹ 9000 .$$ Nandini's monthly salary $=₹(9000 \times 2)=₹ 18000$. Let Kaushal's monthly salary be ₹ $x$. Then, 12\% of $x=16 \%$ of 18000 $$\begin{aligned} & \Rightarrow \frac{12}{100} x=\left(\frac{16}{100} \times 18000\right)=2880 \\ & \Rightarrow x=\left(\frac{2880 \times 100}{12}\right)=24000 \end{aligned}$$
