Best answer

Answer: (a) Shares ₹ 12,000; Mutual funds ₹ 18,000; Bank FD ₹ 24,000; Post ₹ 18,000 (b) ₹ 12,000

Amount = \(\dfrac{\text{central angle}}{360^\circ} \times \text{total}\)

Shares = \(\dfrac{60}{360} \times 72000\) = ₹ 12,000

Mutual funds = \(\dfrac{90}{360} \times 72000\) = ₹ 18,000

Bank FD = \(\dfrac{120}{360} \times 72000\) = ₹ 24,000

Post = \(\dfrac{90}{360} \times 72000\) = ₹ 18,000

Check: 12000 + 18000 + 24000 + 18000 = 72000.

(b) Difference = 24000 − 12000 = ₹ 12,000
