Question

    6 interns together do as much work as a regular employee.

    If 36 interns finish 90 tasks in 3 days, how many regular employees are required to do 90 tasks in 2 days?
    A 28 Correct Answer Incorrect Answer
    B 18 Correct Answer Incorrect Answer
    C 9 Correct Answer Incorrect Answer
    D 40 Correct Answer Incorrect Answer

    Solution

    ATQ,

    Let the efficiency of each intern be 'x' units/day

    Efficiency of each employee = 6x units/day

    Let the number of employees be 'm'

    (36x × 3)/90 = (6x × m × 2)/90

    ⇒ 12m = 108

    ⇒ m = 9

    Therefore, 9 regular employees are required to do the work in 2 days.
