Question

A clock loses 't' seconds in 'h' hours. If the clock is set correctly at 12:00 noon on Sunday, what time will it show at 12:00 noon on the following Sunday?

• A. $7\left(24\right)\frac{h}{t}$ minutes to 12
• B. $7\left(24\right)\frac{t}{60h}$ minutes to 12
• C. $7\left(24\right)\frac{h}{60t}$ minutes to 12
• D. $\frac{60t}{7}\left(24\right)h$ minutes to 12
• E. None of these

Answer 1

The correct option is B $7\left(24\right)\frac{t}{60h}$ minutes to 12

The clock gains t secs in h hours,
It will gain t/h secs in every 1 hour.
Difference in time = 24*7 hours,
Time lost=7(24)*t/h secs.
time displayed =12:00 - 7(24)*t/h secs a.m.
