Initial 4 days [Billy + Tony + Mike (40%)] + Last 16 days [Tony + Mike (60%)] = Total 20 days From the above statement, it is clear that efficiency of Tony and Mike is 60/16 = 3.75% Efficiency of Billy, Tony and Mike is 40/4 = 10%. It means efficiency of Billy alone is (10-3.75) = 6.25% Now, Tony : Mike Number of days 3 : 4 Efficiency 4 : 3 ∴ Efficiency of Tony = 4/7 ×3.75 = 2.14% Efficiency of Mike = 3/7 ×3.75 = 1.61% Thus the least efficient person is Mike Share of work done by Mike= 1.61 × 10 = 16.1% ∴ Mike’s Share of Amount = 16.1% of 150000 = 24150
