Question

One day has 24 hours. If Robert attends guitar classes for $\frac{1}{8}$ of the day, studies and works for $\frac{2}{8}$ of the day, and plays for $\frac{3}{8}$ of the day, how many hours does he spend on other activities?

• A. 8 h
• B. 13 h
• C. 6 h
• D. 9 h

Answer 1

The correct option is C 6 h

Number of hours in a day = 24
Hours spent attending guitar classes $=24\times \frac{1}{8}$
= 3 h

Hours spent studying and working $=24\times \frac{2}{8}$
$=3\times 2$
= 6 h

Hours spent playing $=24\times \frac{3}{8}$
$=3\times 3$
= 9 h

Total time spent = 3 + 6 + 9
= 18 h

Remaining time = 24 -18
= 6 h
