    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?
    A (11/13) days Correct Answer Incorrect Answer
    B (18/19) days Correct Answer Incorrect Answer
    C (17/13) days Correct Answer Incorrect Answer
    D (18/13) days Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    ATQ, Number of days taken by Amit to finish the target= (6/25) ├Ч 10 = 24 days Number of days taken by a Geeta to finish the target = (6/40) ├Ч 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 ├Ч (15/100) } ├╖ (5 + 8) = (18/13) days
