Mental Math: Bhajan Buys Bricks Bhajan went to buy bricks. The price was given for one thousand bricks. The prices were also different for different types of bricks.
| Old bricks | – Rs 1200 for one thousand bricks |
| New bricks from Intapur | – Rs 1800 for one thousand bricks |
| New bricks from Brickabad | – Rs 2000 for one thousand bricks |
Bhajan decided to buy the new bricks from Brickabad. He bought three thousand bricks. How much did he pay?
• 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
