Question

A is 30% more efficient than B. If it takes A 23 days to complete a work, find how long it will take both A and B to finish the work.

Answer 1

Step-by-step explanation:

Now to make the fraction as like fractions divide the L.C.M. by the denominator of fractions, then multiply both the numerator and denominator of fraction with the number get after dividing L.C.M. As in fraction 1/2 denominator is 2. The ascending order of the fractions is 3/8 < 1/2 < 2/3 < 4/5

Answer 2

Answer:

A takes 23 days to finish. As the Efficiency of B is 1.3 times of A, then B takes 1.3*23 days. X = (13*23)/23 = 13 days. B is the answer
