Marks: +1, -0

The prices of a scooter and a T.V. are in the ratio

7: 5 .

If the scooter costs

\text{Rs. 8000}

more than a T.V. set, then the price of a T.V. set is :

$₹ 20,000$
$₹ 24,000$
$\text{Rs. }28,000$
$₹ 32,000$ .

Solution:

Concept:

Represent the prices using the given ratio

7:5

and equate their difference to

₹ 8000

.

Explanation:

Let the price of the scooter be

7x

and the price of the T.V. be

5x

.

The scooter costs

\text{Rs.} 8000

more than the T.V., so:

7x - 5x = 8000

2x = 8000

x = 4000

Hence, the price of the T.V. set is

5x = 5 \times 4000 = ₹ 20,000

.

Answer:

₹ 20,000
