Question

The total cost of a bicycle and a radio is Rs.7000. If the cost of the bicycle is Rs.1000 more than two times the cost of the radio, find the cost if each of the items.​

Answer 1

Answer:

2000/- and 5000/-

Step-by-step explanation:

Total cost=7000/-

let the cost of radio be x

cost of bicycle=2x+1000

x+2x+1000=7000/-

3x+1000=7000/-

1000 transpose

3x=7000-1000

3x=6000

x=6000/3

x=2000(cost of radio)

cost of bicycle=2x+1000

2×2000+1000

4000+1000

5000 is the cost of bicycle

Answer 2

Answer

cost of bicycle is = 5000

and cost of radio is = 2000

Step-by-step explanation:

let the cost of bicycle and radio is be x and y respectively

x + y = 7000

x = 7000 - y .....(I)

2x = y - 1000.....ii

2(7000 - y) = y - 1000

14000 - 2y - y = - 1000

15000 = 3y

so y = 5000

Now puting y on equation I

x = 7000 - y

x = 7000 - 5000

• x = 2000
