• Guess what he will pay if he buys 500 old bricks.
Answer:
Bhajan bought new bricks from Brickabad. Cost of one new brick from Brickabad = Rs 2000
÷1000 = Rs 2 Cost of 3000 new bricks bought from Brickabad = Rs 2
× 3000 = Rs 6000
• Bhajan bought 500 old bricks and the cost of 1000 old bricks = Rs 1200 We have to find the cost of 500 old bricks, which is half of 1000 bricks. Cost of 500 old bricks = Rs 1200
÷ 2 = Rs 600 Thus, the cost of 500 old bricks = Rs 600
Step-by-step explanation:
price of 1000 bricks =1000/-
price of 1 brick = 1000/1000=1
