Question

A man buys a certain number of litchies at 20 per rupee and epual number at 30 per rupee . He mixed them and sold them at 25 per rupee. Find his gain or loss percent. ​

Answer 1

Step-by-step explanation:

He buys x oranges at 20 for Rs.60/-

Each orange will cost 60/20 or Rs.3/-

So cost price of this variety of orange =3x

Similarly he buys x (same quantity) at 30 for Rs.60/-. So cost per orange 60/30 or Rs.2/-

So CP of the 2nd variety = 2x

Total quantity of both varieties :3x+2x = 5x

Total cost of both varieties = Rs.120/-

5x = Rs.120, x = 24

So his average CP is he buys 24 oranges for Rs.60/- or CP per orange =60/24 or 5/2

He sells at 25 oranges for Rs 60 or SP per orange = 60/25 or 12/5

Loss = CP-SP = 5/2-12/5=1/10

Loss Percent = loss/CP x 100

1/10 ÷5/2 x 100 = 1/10×2/5×100 = 4% loss.
