Show answer & explanation
Correct answer: B
A is thrice as efficient as B. And that means A will take 1/3 the time B would take to complete the piece of work.
If A takes x days B would take 3x days and we know that 3x - x = 10 days and therefore x = 5. Which means A would take 5 days and B would take 15 days
