- An amont of 600 crores is spent by the Government in 3 Schemes (A,B,C). Now twice the amount spent on Scheme C together with the amount spent on Scheme A is Rs. 500 crores. Three times the amount spent on Scheme A together with the amount spent on Scheme B and Scheme C is Rs. 1200 crores.Find the amount spent on each scheme using matrices.Read more on Sarthaks.com - https://www.sarthaks.com/547624/an-amont-of-600-crores-is-spent-by-the-government-in-3-schemes-a-b-c
