Show answer & explanation

Correct answer: B

Let the number of questions solved correctly be x.
Then, the number of questions solved incorrectly is 2x.
The total number of questions attempted is x + 2x = 3x.
Given that the total is 48, we have 3x = 48.
Solving for x gives x = 16.
Therefore, the number of questions solved correctly is 16.

हिन्दी उत्तर:
माना सही उत्तर दिए गए प्रश्नों की संख्या x है।
तब गलत उत्तर दिए गए प्रश्नों की संख्या 2x होगी।
कुल प्रश्नों की संख्या x + 2x = 3x है।
दिया गया है कि कुल प्रश्न 48 हैं, इसलिए 3x = 48।
x का मान ज्ञात करने पर x = 16 प्राप्त होता है।
अतः सही उत्तर दिए गए प्रश्नों की संख्या 16 है।
