একক ছাড় = 25%
ধারাবাহিক ছাড় = 15% এবং 10%
পার্থক্য = 25 টাকা।
গণনা:
বিলের পরিমাণ ধরা যাক 100x টাকা
ঘটনা 1:
100x এর উপর 25% ছাড় = 25x ছাড়
ছাড়ের পর দাম = 100x - 25x
⇒ 75x
ঘটনা 2:
100x এর উপর 10% ছাড়= 10x
ছাড়ের পর দাম = 100x - 15x
⇒ 85 x
85x এর উপর 10% ছাড় = 8.5x
দ্বিতীয় ছাড়ের পরে দাম = 85x - 8.5x
⇒ 76.5 x
প্রশ্ন অনুযায়ী,
76.5x - 75x = 25
⇒ 1.5x = 25
⇒ x = 25/1.5
⇒ x = 16.6667
⇒ 100x = 1666.67 টাকা
∴ বিলের পরিমাণ 1,666.67 টাকা ।
