Question
Amit manages to reach 25% of a sales goal in 6 days,
whereas Geeta can achieve 40% of the same goal within the same timeframe. How long would it take for both Amit and Geeta to accomplish 15% of the target collectively?Solution
ATQ, Number of days taken by Amit to finish the target= (6/25) × 10 = 24 days Number of days taken by a Geeta to finish the target = (6/40) × 100 = 15 days Let the total target be 120 units. (LCM of 24 and 15) Efficiency of Amit = (120/24) = 5 units/day Efficiency of a Geeta = (120/15) = 8 units/day Required number of days = {120 × (15/100) } ÷ (5 + 8) = (18/13) days
