Question

. a) If the selling price of a television is 1 2/5 times of its cost price. Find the gain or loss as percent.​

Answer 1

Answer:

Let × be the CP of TV Set

CP = x

SP = (x) × 6/5

= 6x/5

Gain = SP –CP

= 6x/5 – x

= x/5



= (x/5 × 100) / x

= 20%

So, If TV set is sold at 6/5 price of its CP. Then Gain percent will be 20%.

Answer 2

Given:

Selling Price of the television = 1.2/5 times of CP

To Find:

Gain or loss percent

Solution:

Let the cost price of a television be = x

Selling price = 1.2/5

= 7/5

= 1.4x

Now, SP is greater than CP, therefore, there is Gain.

Using the formula to determine gain -

Gain = S.P - C.P

= 1.4x - x

= 0.4x

Calculating Gain %

Gain % = ( Gain × 100)/C.P  

= (0.4x × 100)/x  

= 40

Answer: The gain percent is 40%
