Given : Working time at the office of a man is represented by the shaded portion in a 24 hour clock,
To Find : ratio of working hours to nonworking hours
Solution:
Clock of 24 hrs has been divided in 12 equal parts
Hence each part = 24/12 = 2 hrs
There are 3 shaded parts for Working time at the office
=> Working Time = 3 * 2 = 6 hrs
Non Working Time = 24 - 6 = 18 hrs
ratio of working hours to nonworking hours = 6 : 18
= 1 : 3
