Let the cost price or C.P of the table be Rs.x .

And the given loss percentage while selling is, loss=(100−10)%ofx=90100×x=910x

And, Gain=(100+10)%ofx=110100x=1110x

A dealer gets Rs.940

.

Now, according to the question:

∴Gain−loss=940⇒1110x−910x=940⇒11x−9x10=940⇒2x10=940⇒2x=9400⇒x=4700

Hence, the required cost price of the table is Rs.4700
