Correct Answer - Option 3 : 33 days
Given:
B is twice efficient than A
The total time taken to complete the work by both A and B together is 22 days
Concept used:
Total Work = total efficiency × number of days
Calculation:
B is twice efficient than A
Efficiency ratio of A and B = 1 : 2
Total work = total efficiency × number of days
⇒ 3 × 22 = 66 unit
Number of days required to complete the work along
⇒ Total work / efficiency of B
⇒ 66/2
∴ 33 Days
