Question

by selling 125 dvd is a man gairs amount equal to the selling price of 5 find his gain​

Answer 1

Answer:

Let the CP of each DVD be Rs 1

CP of 125 DVD = 125×1 = 125

now, SP of 125 - CP of 125 = SP of 5

SP of 125 - SP of 5 = CP of 125

SP of 120 = CP of 125

Now CP of 120 = 120×1 = 120

SP of 120 = CP of 125 = 125

Gain = SP - CP = 125 - 120 = 5

Gain% = Gain/CP ×100

= 5/120×100

= 4.166% Ans.
