Question 187
A trader sells 150 metres of cloth for Rs. 6,600 and he sells 300 metres of cloth for Rs. 12,750. How much concession does the trader give per metre of cloth, when he sells 300 metres of cloth?
Solution
Case I : Trader sells 150 metres of cloth for Rs. 6,600
=> S.P. per metre = Rs. $$\frac{6600}{150}$$
= Rs. 44
Case II : Trader sells 300 metres of cloth for Rs. 12,750
=> S.P. per metre = Rs. $$\frac{12750}{300}$$
= Rs. 42.5
$$\therefore$$ Required discount = Rs. (44 - 42.5) = Rs. 1.5
