Question

a table is sold at a profit of 20% if both the cost price and selling price of the table and decreased by rupees 100 the profit 5% more original cost price of the table is​

Answer 1

Answer:

Let CP X.

SP = 1.2X.

When CP is Rs. 100 less,

CP = X - 100

SP = 1.2X - 100.

Now,

1.2X - 100 = 1.24*(X-100)

On Solving, we get

X = 600.

CP = Rs. 600

Answer 2

500

Answer:

Let the Cost price of the table be x

Case 1 - SP = 120x/100 = Rs. 6x/5

Case 2- CP = Rs.(x - 100)

SP = Rs. (6x/5−100)

Profit = (6x/5−x)=Rs.x/5

Therefore, (x/5) / (x−100) ×100=25

=> 25x - 2500 = 20x

=> 5x = 2500

=> x = 500
