Daily workers complete in 40 days 30 x 40 =1,200

Alternative workers complete in 40 days = 20 ×402=400

Now assume, they work x days after 40 days.

That means, alternate workers will work for x2 days.

Total task can be written as

= 1, 200 + 400 + 30x + 20 ×x2 = 2000

= 1, 600 + 30x + 10x = 2

=40x = 400

x=40040=10 days.
