    C 2:3:1 Correct Answer Incorrect Answer
    D 5:1:2 Correct Answer Incorrect Answer

    Solution

    Let the efficiency of A be 100. Given that B is thrice as efficient as A   Efficiency of B = 300 Also given that C is 0.50 times as efficient as A Efficiency of C = 50   From the given data, We need to find the ratio of several days A, B, and C when they work individually LCM of 100, 300, and 50 is 300 Ratio of several days when they work individually.   300/100: 300/300: 300 /50 =3:1:6.
