ఇచ్చినది:

అత్యధిక స్కోరు మరియు అత్యల్ప స్కోరు 55 తేడాతో ఉంటాయి.

గరిష్ట మార్కులు కనీస మార్కులకు 9/4 రెట్లు

లెక్కింపు:

అత్యధిక స్కోరు x మరియు అత్యల్ప స్కోరు y గా ఉండనివ్వండి

ప్రశ్న ప్రకారం

x – y = 55

⇒ x = 55 + y     ---- (1)

అలాగే, x = (9/4) y

⇒ 4x = 9y

⇒ 4x – 9y = 0

సమీకరణం (1) నుండి x విలువను ఉంచగా, మనకు లభిస్తుంది

4(55 + y) – 9y = 0

⇒ 220 + 4y – 9y = 0

⇒ 5y = 220

⇒ y = 44
