Explanation

Shirts produced in year 2016 = 2.8 Lakh. Percent of shirts passed in quality test = 100 – 1.25 = 98.75% ⇒ Total no of shirts that passed the quality test = 2.8 × 98.75/100 = 276500. Shirts produced in year 2017 = 3.6 Lakh. Percent of shirts passed in quality test = 100 – 1.25 = 98.75% ⇒ Total no of shirts that passed the quality test = 3.6 × 98.75/100 = 355500 ⇒ Total shirts in year 2016 and 2017 that passed the quality test = 632000. ∴ Average number of shirts that passed the quality test in year 2016 and 2017 = 632000/2 = 316000.
