A can complete a work in 11 days and B can complete the same work in 26 days. If they work together, in how many days will the work be completed? MCQ with Answer and Explanation

Explanation:
Combined time for full work multiplied by 0.75 = 5.98 days.

Explanation:
Remaining work = (1 - 5*(1/11+1/22))×100 = 31.82%.

Explanation:
Total work = LCM(20, 30) = 60 units. Efficiency of A = 3, B = 2. In a 2-day cycle (A then B), work completed = 3 + 2 = 5 units. Number of cycles required = 60 / 5 = 12 cycles. Total time = 12 * 2 = 24 days.
