  1. (i) Both have equal flexibility scores (65). Keerthi scores 5 marks lower in strength (weight 4) but 5 marks higher in agility (weight 6). Since agility holds greater weight, Keerthi’s total is higher. (ii) Rashi’s score is [(60 × 4) + (65 × 5) + (70 × 6)] / 15 = 985/15 ≈ 65.67. Keerthi’s score is [(55 × 4) + (65 × 5) + (75 × 6)] / 15 = 995/15 ≈ 66.33.
