Under the Miller-Orr model, the lower cash limit is ₹20,000, the variance of daily net cash flows is ₹9,00,000 (standard deviation ₹949.87 is not required), the transaction cost is ₹50 per transaction and the daily interest rate is 0.025%. Using the formula Spread = 3 × [(3/4 × transaction cost × variance) / interest rate]^(1/3), what is the spread (nearest ₹)?

The spread works out to about ₹15,390, using three times the cube root of 0.75 × 50 × 9,00,000 divided by 0.00025.

  2. B₹4,500Correct
  3. C₹6,000
  4. D₹9,000

Explanation

Inside bracket: 0.75 × 50 × 900,000 = 33,750,000; divided by 0.00025 = 135,000,000,000. Cube root = 5,130 approximately (5130³≈1.350×10^11). Spread = 3 × 5,130 = 15,390. This does not match any option, so recompute carefully is needed; the intended data gives a different result.
