Explanation

Let the total number of workers be ‘x’, then according to the question, Skilled workers = 75% of x Unskilled workers = (100-75)% = 25% of x, Permanent workers = 20% of unskilled workers + 80% of skilled workers = 20% of 25% of x + 80% of 75% of x = x × (20/100) × (25/100) + x × (80/100) × (75/100) = x {0.05 + 0.6} = 0.65x According to the question, remaining workers are temporary whose number is 126, ⇒ (1 - 0.65)x = 126 ⇒ 0.35x = 126 ⇒ x = 126/0.35 = 360 Hence, the required number of workers is 360.
