RD SharmaSolutions for Class 8 Maths Chapter 11 Time and Work


RD Sharma Solutions for Class 8 Chapter 11 “Time and Work”- The basic concept of Time and Work is similar to that across all Arithmetic topics, i.e. the concept of Proportionality. Efficiency is inversely proportional to the time taken when the amount of work done is constant. Hence, if A finishes work in 4 days, it means- in 4 days he will do 100% of the work.
