Question: The rates of interest in two banks A and B are inthe ratio `5 : 4. A person wants to deposit his total savings in two in such a way that he received equal fafl yearly interest from both. He should deposit the savings in banks A and B in the ratio :
A
B
C
D
`2 : 5`
B
`4 : 5`
C
`5 : 2`
D
`5 : 4`
Note: Let the savings be X and Y and the rates of simple interest be `5x` and `4x` respectively.
Then,
`x xx 5x xx 1/2 xx 1/100`
`= y xx 4x xx 1/2 xx 1/100`
`or x/y = 4/5`.
`i.e.X : Y = 4 : 5
