Question

By selling a table for ₹1320,a trader gains 10%. Find the CP of the table.

Answer 1

Given selling price = Rs 1320
Gain% = 10%
Let CP be Rs x
We know that
CP + gain = SP
⇒ x +(10/100) × x = 1320
⇒ x+ x/10 = 1320
⇒ (10x+x)/10 = 1320
⇒ 11x/10 = 1320
⇒ 11x = 13200
⇒ x = 13200/11
∴ x = 1200
∴ The cost price of the table = Rs 1200
