Question

by selling a table for rs.1320 a trader gains 10 percent.. find the CP of the table

Answer 1

SP = 1320
CP = x
Precent gain = 10%

x + 10% of x = 1320
x + x/10 = 1320
11x/10 = 1320
11x = 13200
x = 1200


Therefore the Cost price is Rs.1200.

Answer 2

Answer:-

Selling Price = 1320

Cost Price = y

10% is the profit:-

y + 10% of y = 1320

y + y/10 = 1320

11y/10 = 1320

11y = 13200

y = 1200

Hence, cost price is 1200 and value of y = 1200.
