সঠিক উত্তর: Option C
cost for printing 1000 copies is 7500 tk cost for printing 2500 copies is 15000 tk so, cost for printing (2500-1000)=1500 copies is (15000-7500) tk =7500 tk here, cost for printing 1500 copies is 7500 tk cost for printing 1 copies is 7500/1500 tk cost for printing 1000 copies is 7500 x 1000/1500 tk=5000 tk
