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?
[ A ]
[ B ]
[ C ]
[ D ]
[ E ]
None of these
SP of 150 metres of clothes = Rs.6600
SP of 1m cloth = Rs. $6600 \over 150$ = Rs.44
SP of 300 metres of cloth = Rs.12750
SP of 1m cloth = Rs.$12750 \over 300$ = Rs.42.5
Concession = Rs. (44 - 42.5) = Rs.1.5
