A) 4 p.m.
B) \[59\frac{7}{12}\] minutes past 3
C) \[58\frac{7}{11}\] minutes past 3
D) \[2\frac{3}{11}\]minutes past 4
Correct Answer: A
Solution :
Time from 7 a.m. to quarter pass 4 = 9 hours 15 min. = 555 min. - Now, \[\frac{37}{12}\]mm. of this watch = 3 min. of the correct watch. 555 min. of this watch \[=\left( \frac{3\times 12}{37}\times 555 \right)\]min. \[=\left( \frac{3\times 12}{37}\times \frac{555}{60} \right)\]hrs. = 9 hrs. of the correct watch. Correct time is 9 hours after 7 a.m. i.e., 4 p.m.
