The graph below shows total profit, labour cost and profit (in crore Rs.) of four different companies P, Q, R and S. Total cost is defined as the sum of labour cost and raw material cost. Read the graph and answer the questions.
By observing the graphs and remembering that the total cost is a sum of labour cost and raw material cost, we can see that S had the highest raw material cost (total cost-labour cost), which is 40 cr.
