उत्तर
Identify the formula for the fitness index score:
Fitness Index = `("Duration of exercise in seconds × 100")/("2 × (Sum of pulse counts in recovery period)")`
Determine the duration of exercise: 275 seconds.
Determine the sum of pulse counts in the recovery period: 100 (since it is given as the pulse rate in 1-1.5 minutes after exercise).
Substitute the values into the formula:
Fitness Index = `(275 xx 100)/(2 xx 100) = 27500/200 = 137.5`
The fitness index score of Mr. X is 137.5.
