Answer:

Step-by-step explanation:

Part I 6.00% per annum ------------- Amount invested =x

Part II 8.00% per annum ------------ Amount invested = y

Total ---- 55000

Interest----- 3900

Part I 6.00% per annum ---x

Part II 8.00% per annum ---y

Total investment

x + 1 y= 55000 -------------1

Interest on both investments

6.00% x + 8.00% y= 3900

Multiply by 100

6 x + 8 y= 390000.00 --------2

Multiply (1) by -6

we get

-6 x -6 y= -330000.00

Add this to (2)

0 x 2 y= 60000

divide by 2

y = 30000

Part I 6.00% Rs 25000

Part II 8.00% Rs 30000
