She noticed time twice during her workout, once after completion of 10% of Exercise as 24 minutes 18 seconds. Calculate the time she must have noticed when she had completed 40% of her workout? Correct Answer 16 minutes 12 seconds

⇒ If Himani noticed time first time after 10% completion of her workout. That means, she has 90% of her workout remaining.

⇒ 24 min 18 sec presents 90% of her total workout.

⇒ let us assume that her total workout be ‘t’ minutes

⇒ 24 + 3/10 = (9/10) t

⇒ 243/10 = (9/10) t

⇒ (243/10) × (10/9) = t

⇒ t = 27 min (Himani’s full workout)

⇒ If she has completed 40% of her workout, she has 60% of her workout remaining.

If her full workout is 27 minutes,

⇒ 60% of this value is (0.60 × 27) = 3/5 × 27 = 81/5 = 16 minutes 12 sec

∴ Answer is 16 minutes 12 sec
