Question
Anand is capable of finishing a task in 36 days when
working solo. Akash, being 40% more efficient than Anand, can accomplish tasks quicker. Calculate how many days it would take for Anand and Akash to complete the work if they collaborate.Solution
Let the efficiency of Anand = '5x' units/day Then, total work = 5x X 36 = '180x' units Efficiency of Akash = 5x X 1.4 = '7x' units/day Combined efficiency of Anand and Akash = 5x + 7x = '12x' units/day So, time taken to complete the entire work = 180x ÷ 12x = 15 days Hence, option a.
