Answer 1

Answer:

Rs.275

STEP BY STEP EXPLANATION:

A Trader loses 10% on his cost price.

For simplicity,

Let us assume CP = 100x and SP = 90x

Then Ratio of CP:SP = 10x:9x

Given,

SP= 9x = 225 Rs

or, x= 25Rs

Therefore,

CP= 10x = 10x25

=250Rs

Again, 10% gain on CP is provided.

So, corresponding ratio will be =

CP:SP= 10:11

So, CP = 10x = 250

x= 25

SP = 11x = 11x25

=275 Rs

So, the price per kg should be sell to gain 10% on his cost price is Rs.275 per kg
