Answer: Option E

Explanation:

To find the nearest ending balance, we can use the formula for compound interest:

A = P * (1 + r/n)(n×t)

where: P = Tk. 1,000 (the initial investment) r = 10% (the annual interest rate) n = 12 (compounded monthly) t = 10 years

Plugging in the values, we get:

A = 1000 × (1 + 0.1/12)(12×10) ≈ Tk. 2,594.49

Therefore, the nearest ending balance at the end of 10 years is approximately Tk. 2,594.49.

So, answer is None.

Answer: Option C

Explanation:

The initial position of the plane along with their final positions will make a right - angled triangle and the hypotenuse of that triangle will be the direct distance between them at 3 pm. Now, travel time from 1 pm to 3 pm is 2 hours.

So, distance covered towards North = 150 x 2 = 300 miles and towards west = 200 x 2 = 400 miles.

Therefore, their direct distance = (3002 + 4002)1/2 = (90000 + 160000)1/2 = 2500001/2 = 500 miles.
