Let the number of employees earlier = ‘3a’ Then, number of employees now = ‘2a’. ∵ Average salary of employees earlier = ‘4b’, ∴ Average salary of employees now = ‘5b’. ⇒ Total salary of employees earlier = 3a × 4b = 12ab ⇒ Total salary of employees now = 2a × 5b = 10ab ∴ Difference = 12ab – 10ab = 2ab Given that, ⇒ 2ab = 12,000 Then, initial expenditure = 12ab = 2ab × 6 = 72000Related questions
