    A and B started a business with initial investments in the ratio 12 : 11 and their annual profits were in the ratio 4 : 1. If A invested the money of 11 months, B invested the money for

    A) 3 months

    B) 4 months

    C) 5 months

    D) 7 months

    Correct Answer: A

    Solution :

    [a] Let the investments of A and B be Rs. 12x and Rs. 11x, respectively. Suppose B invested the money for y months. Then, \[A:B=(12x\times 11):(11x\times y)\] \[=(132x:11xy)=12:y)\] \[\therefore \] \[\frac{12}{y}=\frac{4}{1}\]\[\Rightarrow \]\[4y=12\]\[\Rightarrow \]\[y=3\] Hence, B invested the money for 3 months.
