Solution: অনুবাদঃ Photocopy'র দোকানে প্রথম 10 কপি করতে x টাকা খরচ হয় । পরবর্তী 50 কপির প্রতি কপির জন্য x এর চেয়ে 2 টাকা করে কম খরচ হয় । 61 তম কপি থেকে প্রতি কপির জন্য 1 টাকা করে লাগে । 200 কপি Photocopy করতে কত টাকা লাগবে ? (x এর সাপেক্ষে) । প্রতি কপি x টাকা করে 10 কপিতে খরচ হবে 10x টাকা । পরবর্তী 50 কপিতে খরচ = 50(x - 2) = (50x - 100) টাকা পরবর্তী বাকি (200 - 60) বা 140 কপিতে খরচ 140 1 = 140 টাকা 200 কপিতে মোট খরচ = 10x + (50x - 100) + 140 = 60x + 40 টাকা ।Related questions
