Answer 1

Answer:

Gain=25%

Step-by-step explanation:

Given SP of 12 oranges = CP of 15 oranges

Let the cost price of 15 oranges = x

So, the cost price of one orange = x/15

Again, SP of 12 oranges = x

So, SP of one orange = x/12

Now, Gain = SP of one orange - CP of one orange

=> Gain = x/12 - x/15

=> Gain = (5 - 4)x/60

=> Gain = x/60

Now, Gain% = (Gain * 100)/CP

=> Gain% = {(x/60) * 100}/(x/15)

=> Gain% = (15 * 100)/60

=> Gain% = 100/4

=> Gain% = 25 %
