Number of technicians × studio A × days = Number of technicians × studio B × days ⇒ 5 × studio A × 30 = 8 × studio B × 15 ⇒ 5 × studio A = 4 × studio B ⇒ Studio A/Studio B = 4/5 ⇒ Time taken by one technician of studio A and one technician of studio B together to complete the work = (5 × 4 × 30)/(4 + 5) ⇒ Time taken by one technician of studio A and one technician of studio B together to complete the work = 200/3 days ∴ Total work will be done by one technician of studio A and one technician of studio B together in 200/3 days.
