Question : A boat covers 12 km upstream and 18 km downstream in 3 hours, while it covers 36 km upstream and 24 km downstream in $6\frac{1}{2}$ hours. What is the speed of the current?
Option 1: 1.5 km/hr
Option 2: 1 km/hr
Option 3: 2 km/hr
Option 4: 2.5 km/hr

Option 1: 48.8%
Option 2: 51.2%
Option 3: 54%
Option 4: 60%
Correct Answer: 48.8%

So, the value after 3 years = $P(1-\frac{20}{100})^3$ = $P(1-\frac{1}{5})^3$ = $P(\frac{4}{5})^3$ = $P(0.8)^3$ = $0.512P$ So, the required
