Best answer

Answer: (a) Rs. 12,000 (b) Rs. 1,000

(a) Shares are shown by a central angle of 60°, i.e. \(\dfrac{60}{360} = \dfrac{1}{6}\) of the total investment.

\(\dfrac{1}{6}\) of total = 2,000, so total investment \(= 2{,}000 \times 6 =\) Rs. 12,000.

(b) Post is shown by 30°, i.e. \(\dfrac{30}{360} = \dfrac{1}{12}\) of the total investment.

Amount invested in Post \(= \dfrac{1}{12} \times 12{,}000 =\) Rs. 1,000.
