c. 1160, 1840 d. 1080, 1920​

Answer 1

Answer:

D. 1080, 1920

Step-by-step explanation:

Let one part be Rs. x

then the other part is Rs. (3000 - x)

According to the question,

x×4×8/100 = (3000-x)×2×9/100

or, 32x = 54000- 18x

or, 50x = 54000

or, x = 1080

Therefore one part is Rs. 1080 an other part is (3000-1080)= Rs. 1920
