সর্বোচ্চ স্কোর এবং সর্বনিম্ন স্কোরের অন্তর 55
উচ্চতরটি নিম্নের চেয়ে 9/4 গুণ ছিল
গণনা:
ধরা যাক, সর্বোচ্চ স্কোর x এবং সর্বনিম্ন স্কোর y
প্রশ্ন অনুযায়ী
x - y = 55
⇒ x = 55 + y ---- (1)
এছাড়াও, x = (9/4) y
⇒ 4x = 9y
⇒ 4x – 9y = 0
সমীকরণ (1) থেকে x এর মান স্থাপন করে আমরা পাই
4(55 + y) – 9y = 0
⇒ 220 + 4y – 9y = 0
⇒ 5y = 220
⇒ y = 44
