Answer 2

Answer:

There is a gain of 50%.

Step-by-step explanation:

Given : If the selling price of 10 balls is equal to the cost price of 15 balls.

To find : The profit or loss percent ?

Solution :

Selling price 'SP' of 10 balls = Cost price 'CP' of 15 balls

Let us take the cost price of 1 ball be Rs.1

CP of 15 balls =Rs.15

CP of 10 balls should be Rs.10

But here,

SP of 10 = CP of 15 balls

and the cost of SP is Rs.15

Gain = SP-CP

Gain = 15-10

Gain = 5

$G \% = \dfrac{G}{CP}\times100$

$G \% = \dfrac{5}{10}\times100$

$G \% =50\%$

Therefore, There is a gain of 50%.
