Question

The price of a scooter and a tv are in ratio 7:5.if scooter cost rs 8000 more than a tv set then the price of tv set is?

Answer 1

Answer:

The price of the TV set will be Rs 20000

Solution:

Given scooter and TV ratio is 7:5.

Assume price of TV is x

Price of scooter is Rs 8000+ x

Here, 7y = 8000 + x, 5y = x

$\begin{array} { c } { \frac { 7 y } { 5 y } = \frac { 8000 + x } { x } } \\\\ { 7 x = ( 8000 + x ) 5 } \\\\ { 7 x = 40000 + 5 x } \\\\ { 7 x - 5 x = 40000 } \\\\ { 2 x = 40000 } \\\\ { x = \frac { 40000 } { 2 } } \\\\ { x = R s 20000 } \end{array}$

The price of the TV set = Rs 20000

The price of the Scooter= x + Rs 8000

= Rs 20000 + Rs 8000

The price of Scooter = Rs 28000

Answer 2

Answer:

Price of the T.V = Rs 20000

Step-by-step explanation:

Given ,

The price of a scooter and a tv are in ratio 7:5

Let price of the scooter =Rs7x

price of the TV = 5x

According to the problem given,

The scooter cost Rs 8000 more than a TV set .

7x-5x=8000

=> 2x = 8000

/* Divide each term by 2 , we get

=> x = 4000

Therefore,

price of the TV = 5x

= 5×4000

= Rs 20000
