AI explanation

Using the efficiency ratio method, let the work done by Bashir in one day be 1 unit, so Asif does 2 units in one day. Their combined daily work becomes 3 units, which completes the job in 30 days, meaning the total work is 90 units. To find the time Asif takes alone, divide the total work by his daily capacity of 2 units. The result is 45 days.
