Question

A clock is set right at $8:00a.m$. The clock gains $10$ minutes in $24$ hours. What will be the right time when this clock indicates $1p.m$ on the following day?

• A. $11.40p.m$
• B. $12:00p.m$
• C. $10:00p.m$
• D. $12:48p.m$
• E. $Noneofthese$

Answer 1

Answer: (D)

$12:48p.m$

The clock gains $10$ mins in $24$ hours,
It will gain 1 min in every $2.4$ hours.
Difference in time the clock indicates=$1$ p.m.-$8$ a.m. (the next day)
=$29$ hours,
Time gained=$\frac{29}{2.4}=12$ mins.
Actual time=$12:48$ p.m.
