Answer 1

Answer:

13 1/3

Step-by-step explanation:

Given,

Aman, Amit and Ajay together can finish a piece of work in 4 days

Aman+Amit+Ajay=1/4

If  Aman alone can finish it in 8 days and Amit can finish it in 20 days,

Aman=1/8

Amit=1/20

Ajay=1/4-Aman-Amit

Ajay=1/4-1/8-1/20

Ajay=10-5-2/40

Ajay=3/40

Ajay= 13 1/3
