Semeer x 20 days completes the work =:100% performance one days work is 5 %

Mohit can finsh the same amount of work in 24 days = 80% efficience perfomance

Binesh can finish the same amount of work in 36 days = 64 % efficiency performance,ģ

Sammer? Spelling mistake first works for 5 days , Therefore before he left job was 25 % complete. And 75 % of the work is outstanding is 75% remains

So Mocit & Binesh are to complete the remainig 75 % work content, based on Ssmeers performancr

Mohit 3/4 of 24 days = 18 days 18÷ 3 = 6 ( 6 days or 25 % carried out by Smeer)

Binesh 3/4: of 36 days = 27 days 27÷ 3 = 9 ( 9 days or 25% carried out by Smeer)

Answer = 15 days working together = combined work efficiency 80% & 64 % = 144% of Semeers 100%

15 days at 100 = 1500 / 10.3 days × 144 = 1500

Mohit 80 % and Binesh 64% working together is combined performance of144 %

require 10.3 days instead of Sameer 15 days at 100 %
