Given:

p = (0.001) + 3(0.1)(0.99) + (0.3)(98.01) + (9.9)(98.01)

Calculation:

p = (0.001) + 3(0.1)(0.99) + (0.3)(98.01) + (9.9)(98.01)

⇒ p = 0.001 + 3 × 0.1 × 0.99 + 0.3 × 98.01 + 9.9 × 98.01

⇒ p = 0.001 + 0.297 + 29.403 + 970.299

⇒ p = 0.001 + 0.297 + 29.403 + 970.299

⇒ p = 1000

⇒ p/25 = 1000 / 25 = 40

∴ The correct answer is option (3).
