Correct Answer: 3
Solution: (3)
S.I. $=\frac{\text { Principal } \times \text { Time } \times \text { Rate }}{100}$
According to the question,
$ \begin{aligned} & \frac{12000 \times 10 \times r}{12 \times 100}+\frac{16000 \times 9 \times r}{12 \times 100} \\ & = 22000 \\ \Rightarrow & 100 r+120 r=22000 \\ ⇒ & 220 r=22000 Ω \end{aligned} $
$\Rightarrow r=\frac{22000}{220}=100%$ per annum
$\therefore$ B’s share $=120 r=120 \times 100$ $=$ Rs. 12000
