Key Concepts & Formulas

  • 1Clock Angle: Angle = |30H - (11/2)M|.
  • 2Minute hand moves at 6 deg/min. Hour hand moves at 0.5 deg/min.
  • 3Normal years have 1 odd day. Leap years have 2 odd days.
  • 4A year is a leap year if divisible by 4 (and not by 100 unless by 400).

TCS NQT Style Practice Questions

Practice Question 1

Find the angle between hour and minute hands at 3:30.

A) 75 degrees
B) 90 degrees
C) 60 degrees
D) 80 degrees

Correct Answer: A) 75 degrees

Step-by-step Solution: Angle = |30(3) - (11/2)(30)| = |90 - 165| = |-75| = 75 degrees.

Practice Question 2

If 1st January 2001 was a Monday, what day was 1st January 2002?

A) Tuesday
B) Monday
C) Wednesday
D) Sunday

Correct Answer: A) Tuesday

Step-by-step Solution: 2001 is a normal year (not a leap year). A normal year has 365 days = 52 weeks and 1 odd day. Therefore, the day shifts by 1 day, making it a Tuesday.

Study Pro-Tip

Clock angle formula |30H - 5.5M| works for any time, even when the angle is reflex.
