Question

By selling a table in Rs. 3120, I lose
20%. Find the C.P. of the table.​

Answer 1

Answer:

Let cost of one table is c.

=> The cost of other will be (3120 - c)

Now 0.85c = 1.36(3120 - c)

2.21c = 4243.20

=> c = 1920

Cost of other table = 1200.

Answer 2

Answer:

Step-by-step explanation:

SP = Rs.3120

Loss % = 20

Loss % = (CP - SP)/100

(CP-SP)/100 = 20

(CP-3120)/100 = 20

CP-3120 = 20x100 = 2000

Thereefore, CP = 2000+3120 = Rs.5120
