A and B can complete a work in 16 days and 12 days respectively. Both work for 4 days and then A leaves. Find how much time will B take to complete the remaining work?
5 days
The correct answer is 5 days.
If someone is twice as efficient, they have double the work rate and can complete the work in half the time (assuming they work alone). Problems can involve more than two people, or varying work rates, or situations where people join or leave at different times. The fundamental approach remains calculating daily work rates, finding work done, and then calculating remaining work or time. Understanding the concept of fractions is crucial for solving these problems quickly, as work rates and portions of work are often represented as fractions.
