প্রদত্ত:

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
