1. Let fraction of work completed by a man per day be x (so x<1)

   Given that 20*x*12=1 →(1)

   since 1 means complete work}

   Now ater 6 days 5 workers left.

   So work completed till 6th day = 1/2

   So work left = 1/2

   Let no of days needed to complete remaining work be Y

   So (20–5) * x * Y = 1/2 →(2)

   Here 20–5 is no of workers left

   And 1/2 is remaining work

   now divide (1) with (2)

   We get,

   (20*12)/(15*Y) =2

   => 240= 30*Y

   So Y= 8

   So with number of days took to complete entire work = 6(with 20 workers)+ 8(with 15 workers) = 14 days

   Hope it helped

   Thanks for reading:)
