Question

If the time is now $4$ O' clock, what will be the time $101$ hours from now?

• A. $9$ O' clock
• B. $8$ O' clock
• C. $5$ O' clock
• D. $4$ O' clock

Answer 1

After 24hrs , time will again be 4 o'clock. 101%24=5 Hence time after 101 hours will be 9 o'clock

Answer 2

$101$ hrs = $96+5$ hrs

$\qquad \qquad = 4 \hspace{0.1cm} day\hspace{0.1cm} 5\hspace{0.1cm} hrs$ $[∵ 96\hspace{0.1cm} hrs = 24 \times 4\hspace{0.1cm} hrs = 4 \hspace{0.1cm} days]$

∴ If the time is now $4'o \hspace{0.1cm} clock$

so after $101\hspace{0.1cm} hrs$ i.e. $4 \hspace{0.1cm}days$ & $5\hspace{0.1cm} hrs$, the time should be $9'o \hspace{0.1cm} clock$
