Suppose, there are only three firms in a hypothetical economy, viz. A, B and C. During a given period of time, the following transactions were undertaken by them:
(I) Firm A sold goods worth ₹2,000 to Firm B and ₹1,200 to Firm C.
(II) Firm B sold goods worth ₹1,100 to Firm A and ₹3,500 to Firm C.
(III) Firm C sold to households for final consumption, goods worth ₹5,700.
