Step-by-step explanation:
Let total works =x
A takes 24 days to complete x
⇒ In one day a complete work =
24
x
B completes x works in 30 days
⇒ In 1 day B completes work =
30
x
If A and B work together,
work done in one day =
24
x
+
30
x
=

Answer:
13 days
Step-by-step explanation:
A can finish in 24 days
B can finish in 30 days
TW = LCM(24, 30) = 120
eff A = 5
eff A = 4
eff A+B = 9 unit
Now Time = TW/eff = 120/9 = 13.33 days = 13 days (approx)
