Answer :

Let the amount invested at 10% per annum and 8% per annum be x and y respectively.


According to question -


Annual Interest on amount x + Annual Interest of amount y = Rs. 1350



10x + 8y = 135000


5x + 4y = 67500.....(1)


and,


Annual Interest on amount y + Annual Interest of amount x = Rs. 1305



8x + 10y = 130500


4x + 5y = 65250.....(2)


From equation (1), we get -


x = (67500 - 4y)/5.....(3)


Substituting the value of x in equation (2), we get -




(9/5)y = 11250


y = 6250


substituting the value of y in equation (3), we get -


x = 8500


Thus, the amount invested at 10% per annum = Rs. 8500 and,


the amount invested at 8% per annum = Rs. 6250
