Answer: Option B

Explanation:

The minute hand of a clock completes a full revolution of 360 degrees in 60 minutes, which means it moves 360 degrees in an hour.

To determine how many degrees the minute hand moves in 20 minutes, we can calculate the fraction of a full revolution that corresponds to 20 minutes.

20 minutes is one-third of an hour since 20 minutes / 60 minutes = 1/3.

Therefore, the minute hand moves one-third of a full revolution, which is one-third of 360 degrees:

(1/3) * 360 degrees = 120 degrees.

So, the minute hand moves 120 degrees in 20 minutes.

The correct answer is B. 120°.

Answer: Option E

Explanation:

FV=p×r(1+r)n−1

Where:

FV is the future value (Taka 1,00,000 in this case),
P is the annual payment (the amount you deposit every year),
r is the annual interest rate (expressed as a decimal, so 12%=0.12),
n is the number of periods (5 years in this case).
Plugging in the values:

1,00,000=P×0.12(1+0.12)5−1

1,00,000=P×0.12(1.12)5−1

Now, calculate (1.12)5:

(1.12)5≈1.76234

1,00,000=P×0.121.76234−1

1,00,000=P×0.120.76234

1,00,000=P×6.35283

Now, solve for P:

P=1,00,000/6.35283
P≈15,741.01
