Step-by-step explanation:
Let the first part be Rs. x. Second part =(3000−x) ∴S.I. on x at 8% per annum for 4 years=
x×8×421
1005025
=
8x
25
S.I. on (3000−x) at 9% per annum =
(3000−x)×9×21
10050
=
27000−9x
50
∴
8x
25
=
27000−9x
50
=>8x=
(27000−9x)×251
502
=>16x=27000−9x =>16x+9x=27000 =>x=
270001080
251
=1080 ∴First part = Rs.1080

Answer:
1500 + 1500 = 3000
In mathematics, a polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. An example of a polynomial of a single indeterminate x is x² − 4x + 7.
