Answer 1

Answer:

Step-by-step explanation:  cost price ratio of scooter and tv is = 7:5

Let, cost price of scooter is = 7x

    and cost price of tv is = 5x

then cost price of scooter  more than tv is = 7x-5x = 2x

But , scooter costs f8000 more than t.v

so ,  2x=8000

divide by 2 on both sides

x=4000

now , cost price of scooter is  7x= 7*4000 = 28000

  and cost price of t.v is 5x = 5*4000 = 20000
