PRICE CALCULATION OF BRICKS:

Example:

If 2000 rupees is the price of 1000 bricks and Bhajan required 500 bricks then how much he need to Pay.

Solution:

1000 Bricks price is = Rs 2000

1 Brick’s price is      = Rs 2000/1000

500 Bricks price is = (2000/1000) x 500

                             = (2) x 500 = Rs 1000

So, Bhajan needs to pay Rs 1000 for 500 bricks.
