Answer 1

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

=

120

5x+4x

=

120

9x

=

40

3x

Let they take n days to complete entire work.

⇒ Total work =n×

40

3x

=x

⇒n=

3

40

days

Answer 2

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)
