Question

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 interest per year from both. He should deposit the savings in banks A and B in the ratio

• A. 2 : 5
• B. 4 : 5
• C. 5 : 2
• D. 5 : 4

Answer 1

The correct option is B 4 : 5

Rate of interest is 5x and 4x
Let Person invest Rs. P in bank A
And Rs.Q in bank B
Then $\frac{P\times 5x\times 1}{100}=\frac{Q\times 4x\times 1}{100}$
$5P=4Q$
$P:Q=4:5$
