Simple. 13 days.How?
Well here goes,
A is 30% more efficient than B : A + 0.3A =1.3A
Work done by A in one day: 1/23
Work done by B in one day: 1/(1.3*23) = 1/29.9
Work done by A+B in one day: 1/23 + 1/29.9 = 1/13
If both of them worked together, it would take them 13 days.
hope it you satisfied with my answer
