Answer:

8)40

Step-by-step explanation:

(dear questionare I have not studied the chapter of square roots and cube roots because it is not an our syllabus and I am in class 7th so I can answer your 8th question)

let the numbers be 3x + 4x + 5x.

3x+4x+5x=480 (I added all the variable numbers)

12x=480

x=480/12 (I divided)

=40
