Answer 1

Answer:

A merchant sold a cycle at a loss of 20% instead if you had sold it for 450 more he would have made 10% profit. What is his cost price?

Summer side up with saraf furniture!

Solution:-

Assume the cost price is x.

So the sell price of cycle is x-20x/100 =4x/5

Now According to condition…

Sell Price + 450 = Cost Price + 10 % profit

So the algebric equation is following..

4x/5 + 450 = x + 10x/100

(4x+2250)/5 = 11x/10

4x+2250 = 11x/2

11x = 8x + 450

After solving the equation

x = 1500

The cost price is 1500.
