Hope my answer helps you :)

See this problem, you can find your answer on your own:-

Question:

Two equal sums of money were invested, one at 4% and the other at 4 1/2%  . At the end of 7 years, the simple interest received from the latter exceeded than that received from the former by Rs. 31.50. What was each sum?

Answer:-

Then,  x×4.5×7/100 -   x×4×7/100  = 31.50

⇒  31.5x/100  −  28x/100  = 31.5

⇒  3.5x/100  = 31.5

⇒  31.5×100/3.5  = Rs. 900

Thank you :)
