Answer 2

{Some corrections in question}

Question : A seller sold two trousers for Rs 900 each, in one he gains 10% and on the he lost 10%. find his total loss % or gain %.

Solution : Now, according to given, seller gain 10 % on first trouser and selling price of trouser is Rs 900.

Now,

⟹ Cost price = (100 * selling price)/(100 + gain %)

⟹ Cost price = (100 * 900)/(100 + 10)

⟹ Cost price = 90000/110

⟹ Cost price = Rs 818.1818182

similarly, seller loss 10 % on second trouser and selling price of trouser is Rs 900.

⟹ Cost price = (100 * selling price)/(100 - loss %)

⟹ Cost price = (100 * 900)/(100 - 10)

⟹ Cost price = 90000/90

⟹ Cost price = Rs 1000

Now,

⟹ Total cost price of both trousers = 818.18 + 1000

⟹ Total cost price of both trousers = Rs 1818.1818182

and

⟹ Total selling price of both trousers = 900 + 900

⟹ Total selling price of both trousers = Rs 1800

Here, we know that cost price of both trousers is greater than selling price of trousers. Hence it's loss

⟹ loss = cost price - selling price

⟹ loss = 1818.1818182 - 1800

⟹ loss = Rs 18.1818182

Now,

⟹ loss % = (loss/cost price) * 100

⟹ loss % = (18.1818182/1818.1818182) * 100

⟹ loss % = 0.01000000001 * 100

⟹ loss % = 1.000000001 %

Answer : Hence, loss % of the seller is 1 %.
