Correct Answer - Option 4 :
\(6\frac{1}{4}\)%
Calculation:
1 day = 24 hours
1 hour = 60 minutes
30 minutes = 0.5 hour
⇒ 1 hour 30 minutes = 1.5 hours
According to question:
⇒ (1.5/24) × 100 = \(6\frac{1}{4}\)%
∴ A period of 1 hour and 30 minutes is \(6\frac{1}{4}\) % of a day.
The correct option is 4 i.e. \(6\frac{1}{4}\)%
