Question

If the cost of 100 bricks is Rs.2000 and 400 bricks are required to build a wall. Then what is the total cost of bricks used to build that wall?

• A. Rs. 800
• B. Rs. 5000
• C. Rs. 8000
• D. Rs. 2500

Answer 1

The correct option is C Rs. 8000

Given, cost of 100 bricks = Rs 2000
So, Cost of 1 brick
$=\frac{2000}{100}=Rs20$

Given, 400 bricks are required to build the wall.
So, Cost of 400 bricks
= Number of bricks x Cost of 1 brick
$=400\times 20=Rs.8000$
