Question

Two identical identical items are sold for Rs.200 each, with 10% gain on one but 10% loss on the other.

What is the net percentage loss or gain?​

Answer 1

Answer:

Loss % = 0.9%

Step-by-step explanation:

Sp of 1st item = 200

profit %=10%

CP of 1st item=(100/100+P%)*SP

=(100/100+10)*200

=100/110*200

=181.8

Sp of second item=200

Loss % =10%

CP of second item=(100/100-L%)*SP

=(100/100-10)*200

=100/90*200

=222.2

Total CP=181.8+222.2

=404.0

Total Sp=200+200

=400

therefore, Loss = CP-SP

=404-400

=4

Loss percent=L/CP*100

=4/404*100

=0.9%
