The rates of simple interest in two banks A and B are in the ratio 5 : 4. A person wants to deposit his total savings in two banks in such a way that he received equal half-yearly interest from both. He should deposit the savings in banks A and B in the ratio. Choose the correct choice from the following options.
A) 2 : 5 B) 4 : 5 C) 5 : 2 D) 5 : 4 E) None of these
Let the savings be X and Y and the rates of simple interest be 5x and 4x respectively.   Then, X × 5x × 1⁄2 × 1⁄100 = Y × 4x × 1⁄2 × 1⁄100 or X⁄Y = 4⁄5   i.e., X : Y = 4 : 5.   Answer 4 : 5
