Question

Find the cost of building 400 bricks to build a wall if the cost of 100 bricks is ₹2000.

• A. 8000

Answer 1

The correct option is A 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
$=400\times 20=Rs.8000$
