Question

Divide 3600 into two parts such that if one part be lent at 9 % per annum and the other at 10% per annum the total annual income is 333​

Answer 1

Answer:

Let's call the two parts of the principal x and y, such that x + y = 3600.

We know that the total annual income is 333, and that the interest rates are 9% and 10% respectively. So we can set up the following equation using this information:

(x9/100) + (y10/100) = 333

This equation states that the total annual income from the two parts of the principal is equal to the sum of the interest earned on each part.

Now we can solve for x or y using the equation x + y = 3600, we get y=3600-x

So we can substitute y=3600-x in the above equation and get

(x*9/100) + ((3600-x)*10/100) = 333

After solving this equation we get x=2400 and y=1200,

So one part is 2400 and the other is 1200
