Correct answer: C. II & III
- A. I & V
- B. I & III
- C. II & III
- D. IV & V
Explanation
Option C gives Sufficient information as using the information in C as the variables provided are similar in this option which can be used for calculationOption A: this option gives three different variables which cannot be used for calculation. (v,w)Option B:this option gives two equations with completely different variables which cannot be used together for calculation. Option D:this option gives two equations with completely different variables which cannot be used together for calculation.
