Answer 1

Answer:

Virat completed the work alone in 15 days.

Step-by-step explanation:

let , Neeraj =x ,Aman=y and Virat be z

• for solving this type of questions : formula is :. xyz/xy+yz+xz = together work of x,y,z.

• 10×12×z ÷10×12+12×z+10×z
• 120×z ÷120+12z+10z
• 120×z / 120 + 22z
• v/120+22z =4/120
• 120z=480+88z
• 480 = 120z-88z

=32z

• 480/32= Z
• z=15

so,

Virat complete the work alone in = 15 days .
