Q: If m : n = 5 : 4, then what will be the value of (m² + n²) : (m² – n²) ?
  • A. 32 : 5
  • B. 25 : 9
  • C. 41 : 9
  • D. 16 : 9
Correct Answer: Option C - Given- m = 5 n = 4 According to the question (m² + n²) : (m² – n²) = (5² + 4²) : (5² – 42² 41 : 9
C. Given- m = 5 n = 4 According to the question (m² + n²) : (m² – n²) = (5² + 4²) : (5² – 42² 41 : 9

Explanations:

Given- m = 5 n = 4 According to the question (m² + n²) : (m² – n²) = (5² + 4²) : (5² – 42² 41 : 9
