Show the answer and the worked solution
Correct answer: C. Chetan
Worked solution
- Amit = 77 + 65 + 82 = 224.
- Bina = 85 + 72 + 68 = 225.
- Chetan = 66 + 90 + 74 = 230.
- Divya = 92 + 58 + 76 = 226.
- The highest is Chetan.
Answer: Chetan.
The idea
Add every row before comparing. The student strongest in one subject is often not the strongest overall.
Shortcut. Measure each mark from 75: Amit +2 − 10 + 7 = −1, Bina +10 − 3 − 7 = 0, Chetan −9 + 15 − 1 = +5, Divya +17 − 17 + 1 = +1. Chetan leads.
Common trap. Divya — she has the top single mark (92 in Maths), but her 58 in Physics holds her total to 226, below Chetan's 230.
