Q. At what time between 7 and 8 will the hands of a clock be in the same straight line but, not together?
  • (A) 5 (5/11) min past 7
  • (B) 5 (4/11) min past 7
  • (C) 5 (3/11) min past 7
  • (D) 5 (2/11) min past 7
βœ… Correct Answer: (A) 5 (5/11) min past 7

Explanation: When the hands of the clock are in the same straight line but not together, they are 30 minute spaces apart.

At 7 o'clock, they are 25 min. spaces apart.

Minute hand must gain only 5 min. space.

55 min. spaces are gained in 60 min.

5 min. spaces would be gained in (60/55) x 5 = 5 (5/11) min

Required time = 5 (5/11) min past 7
