Tom can complete the work in 8 days.
Tom and Jerry together can complete the work in 2(2/3) days.
Calculation:
Total work = LCM( 8, 8/3) = 8 units
Efficiency of Tom = 8/8 = 1 unit per day
Efficiency of Tom and Jerry = (8 × 3)/8 = 3 unit per day
Efficiency of Jerry = 3 - 1 = 2 unit per day
Double work = 8 × 2 = 16 units
Days required by Jerry alone to complete double work = 16/2 = 8 days
∴ Option 3 is the correct answer.
